3.1 FUNCTION PRINCIPLE
3.1.1

REMOTE MONITORING UNIT
TV/TA converts strong voltage and current into 5A/1A and 100V alternating waveforms is

converted into suitable small signals for computer sampling by high accurate convertor, which
are sent to A/D after filtering and become digital signal, finally enter into CUP for calculation. The
device collect 128 points for each cycle wave to get A/D sampling for CT, PT and DC transmitter,
and calculate the AC monitoring value of current, voltage, active power, reactive power, active
kwh, reactive kwh, power factor, frequency and etc. according to discrete expression of N times
equal interval sampling
AC collection input and output are as follows:
Input: Ua, Ub, Uc, U0, Ux, Ia, Ib, Ic, 3I0
Calculate: Ua, Ub, Uc, Uab, Ubc, Uca, U0, Ia, Ib, Ic, I0, P, Q, CosΦ, f, ±kwh, ±kvarh, 31
times harmonic component。
DC collection input are 0-5V, 1-5V signals, output after converting are as follows:
DC1, DC2, DC3, DC4, DC5, DC6。
AC sampling principle is equal interval sampling for a continuous waveform; according to
the sampling theorem the sampling points of a sine wave can describe the characters of the sine
wave completely. Actually voltage and current cannot be pure sine wave and it must include
higher harmonics. Thus more sampling points more accurate, however, for the limit of hardware
actual condition, it is impossible to add sampling points infinitely, so our device choose sampling
of 128 points
As each cycle doing N points sampling, frequency tracking calculation is necessary, or
sampling as per 50Hz cycle will arise error because power frequency is unequal to 50Hz. The
device do frequency tracking calculation and equal interval sampling after adjust sampling
period.
Remote monitoring includes two-meter method and three-meter method and the
monitoring method is shown in the figure:

DC COLLECTION
Sampling signals: DC collection DC1, DC2, DC3, DC4, DC5, and DC6. Device can

complete the monitoring of 6 DC collections which can be voltage input or current input (current
input is extended function). Electrical isolation between DC input and CPU control system is
achieved through DC/DC converter. DC collection is calculated according to the maximum and
minimum of setting values.
3.1.3

REMOTE COMMUNICATION UNIT
Remote communication is introduced by null node, converted into digital signal after

photoelectric isolation and then enters into device to acquire status signal and deflection signal.
For the filter circuit within the collection of remote communication data, the scanning time of the
CUP to remote communication is 0.3125ms to guarantee its resolution less than 1ms, and
record start as deflection begin, thus the signal collection can prevent the contact chatter. In
addition, each signal collection has filed-setting limit to make sure the accuracy of signal function.
After device confirm the status deflection, the first deflection record time is regarded as the
remote communication deflection time. Its time sequence is shown as figure:

device display program can call the remote communication data name to display and print the
remote communication data SOE.
3.1.4

REMOTE CONTROL UNIT
Control operation is ordered by dispatching or local monitoring, and control unit is mainly

responsible for the reception and return to check the order, then according to the correct order to
output corresponding control information, i.e., output the order for switch tripping or closing.
Each remote control output is controlled by CPU, and the operation steps include: select, return
to check and execute, which achieve the output checking of relay, guarantee the safe and
available executing of remote control. Moreover, the device has hardware self-checking latching
function which can prevent error output for hardware damage.

3.1.6

SYNCHRONIZATION FUNCITON
According to settings closing operation can be no check, synchronization check and

no-voltage check, and synchronization check only or no-voltage check only, however, here only
explain the operation process of synchronization check closing.
3.1.6.1 ENTER THE SYNCHRONIZATION CHECK CLOSING PROGRAM
In local method, receive the closing order from management SCM, or in remote method,
receive closing order from upper computer, then set corresponding KK as 1(KK is one of
EEPROM), after receive confirmed signal, enter to operate closing program.
3.1.6.2 NO CHECK CLOSING OPERATION
If configuration no check, the unit will close directly without assessing the differential
condition of voltage and frequency after receive the closing order from upper computer or unit.
3.1.6.3 NO-VOLTAGE CHECK CLOSING OPERATION
If monitoring configuration is no-voltage check closing, after enter into the closing program,
device send out closing order instantly and closing the breaker when line voltage Ux(Uwyzd is no-voltage check setting value)or bus voltage Um, Um3.1.6.4 SYNCHRONIZATION CHECK CLOSING
If configuration is synchronization check closing, and voltage of both sides are higher than
low-voltage blocking value, synchronization check closing operation will be done as the follow
steps:
1)

Voltage difference check: if there is voltage on both side, find out voltage difference. If Ux
is from A,B line voltage(Ux is from analogy of Ubc/Uca), ΔU=Uab–Ux. If Ux is from A
phase voltage(Ux is from analogy of Ub/Uc), ΔU=Ua–Ux. If ΔU ≤Utc (Utc is voltage
difference setting value), it is regarded as qualified. If ΔU Utc, and it still cannot meet the
requirement during the return time of synchronization, that means communication cannot
meet the synchronization condition and have to exit the operation procedure of closing.

2)

Frequency difference check: if voltage difference is qualified, find out frequency difference.
Δf =f1–f2, if Δf ≤ftc(ftc is frequency difference setting value), it is qualified and will go
to phase difference check. If Δf ftc, and it cannot meet the requirement during the return
time of synchronization, that means communication cannot meet the synchronization

condition and have to exit the operation procedure of closing.
3)

Synchronization check closing: go for synchronization check after both voltage and
frequency difference qualified. Compare the time difference of square wave rising edge
between bus voltage and line synchronization voltage to find out phase difference,
calculating once per cycle(about 20ms),and the calculate formula is C 

 360  .Tm is

bus voltage cycle, while Δt is the time difference of square wave rising edge of both side

voltage, and the both unit is ms, so Φc=0.36°fm·Δt。When phase difference is changed from
1800 to 1600 , calculate the closing ahead angle Φt, and the calculate formula is Φt=
×360°=0.36·Δf·tht (Tc is slip dispatch period, is ahead time of synchronization)
4)

Calculate the variable quantity of phase difference for each period: calculate phase
difference Φc each period after find out Φt. To make sure complete the synchronization
check closing in a slip dispatch period and that the phase difference of both side voltage
close to 0 as closing, predicting closing time is adopted, and the concrete operation is as
follow: calculate the variable quantity ΔΦc of a period (the time when calculate the two
phase difference)phase difference Φc by slip dispatch period Tc and bus voltage period
Tm, and the formula is :

 c 
5)

Tc

Predict closing time: when the calculated difference Φct between Φc and Φt is less than
ΔΦc, that is:

ct  c  t  c
Which indicate that Φc will be less than Φt in next calculation, i.e., it will miss the closing
timing of this slip dispatch period, so predicting closing time is necessary. Slipping Φct at this
moment will come to the result Φc=Φt, and the corresponding time of Φct is the delay time from
this moment tyc, which is the predicted closing time. For

Delay closing: Delay will start as soon as figure out tyc , and till tyc closing order will be sent
out, while closing Φc=Φt. After figuring out Φt, monitoring Δf—if Δf change greatly, even
reversed, Φt should be calculate and tyc should be predicted once again. More accurate tyc
should deduct the procedure operation time from frequency sampling to figure out tyc Stop
closing operation and communicate to exit synchronization information if it yet cannot meet
the synchronization condition during synchronization return time. Monitoring frequency
and voltage difference should be together with phase difference check, and it should be
exit and communicate exiting reason if frequency or voltage difference changes to
unsatisfied the condition.

When enter into synchronization check, if ΔUvoltage difference setting value,
Δffrequency difference setting value, Φc≤20 and no less than 20 times distinguish in 1s
all satisfy the condition, it is regarded as loop network power supply and instant closing is
available.
Note: for this device the synchronization function is fixed on remote control 1 closing

3.1.7

ANALOG CALIBRATION
For the hardware in the device, all the components in each channel are fixed parameter.

Thus the disparity of channel component parameter (current, voltage convertor, resistance in
filter circuit, capacitance etc.) cause amplitude and phase error of each channel AC collection
coming from the AC sampling data after fourier-transform. To make sure the accuracy of
sampling, software calibration for A/D channel is necessary. The principle is: the amplitude of AC
coming from the AC sampling data after fourier-transform multiply a calibration coefficient Kx,
and add a calibration angle φx in phase angle to eliminate the effect to AC signals because of
different channel component parameter. The A/D channel calibration is the process to figure out
calibration coefficient Kx of channel amplitude and phase calibration angle φx. The channel
calibration for this device includes manual and automatic, and the first one is to input channel
calibration coefficient and angle by MMI.
Attentions: Channel calibration is very important and only input the gradeⅡpassword of
user can the main microcontroller enter into channel calibration. To avoid big error of sampling
value because of too large AC signal or damage of some channel component, which may cause
abnormal of calibration value Kxi and φxi, the amplitude calibration coefficient is limited in
0.850~1.150, and phase calibration angle φxi is limited in ±8.00°.
1)

Accuracy automatic modulation
Accuracy automatic modulation is used in device maintenance, which is to add a rated

value in each channel and input an equal value to exterior from clavier, then press ―OK‖, herein
this coefficient is read-in EEPROM. The accuracy automatic modulation also includes phase
modulation. (Debug at factory, user does not do it)
2)

Accuracy manual modulation
It is the extension for the first function. When manual modulation is needed, add a rated

value in channel and calculate the coefficient between rated value and displayed value to read-in
EEPROM, finally modulate the accuracy.

TA DISCONNECT AND TV FUSE FAILURE

3.1.8.1 TV FUSE FAILURE ALARM

meeting the terms by setting time limit. When change 0 to 1, communicate input change
information after discriminated as meeting the terms by setting time limit.
In operation, when control power abnormal, and read-in control power abnormal state
signal. When change 1 to 0, communicate input change information after discriminated as
meeting the terms by setting time limit. When change 0 to 1, communicate input change
information after discriminated as meeting the terms by setting time limit.
In operation, when SF6 air pressure abnormal, read-in SF6 air pressure abnormal state
signal. When change 1 to 0, communicate input change information after discriminated as
meeting the terms by setting time limit. When change 0 to 1, communicate input change
information after discriminated as meeting the terms by setting time limit.
In operation, when spring operating mechanism without energy storage, read-in spring
operating mechanism without energy storage state signal. When change 1 to 0, communicate
input change information after discriminated as meeting the terms by setting time limit. When
change 0 to 1, communicate input change information after discriminated as meeting the terms
by setting time limit.
Above are common input fault monitoring. In device actual use, define the remote
communication data after learning about the on-site use.
