1.2 Feeder Fault detection function
F80 can detect and distinguish three types of faults: over-current load, permanent fault and transient fault, the fault detection of these three types are controlled by the special network distribution program preset in the unit. Over-current load: when a line is overloaded but not severe enough to influence safe operation of the line, FTU-F80 will sense that the current excesses the preset “over-current start-up” value and send out an over-current remote signaling alarm. Transient fault: when transient fault occurs, F80 detects and judges according to the preset program that the circuit breaker (C.B) in the substation trips, and after the circuit breaker has successfully reclosed once or several times, the system will clear the fault and resume power supply. The FTU-F80 sends out two kinds of alarm signal: over-current remote signaling and C.B action signaling alarm. Permanent fault: when permanent fault occurs, 80 detects and judges according to the preset program that the circuit breaker in the substation trips, and in case of the circuit breaker failed to reclose once or several times , the circuit breaker will be locked in its tripping mode and the fault cleared off. At this time FTU-F80 sends out three kinds of alarm signals: over-current remote signaling, breaker action and breaker locking. The following are the Protection Function build into the FTU: • Overcurrent (ANSI 50/51, 50G/51G) • Sensitive earth fault (ANSI 50SEF) • Directional relay (ANSI 67) • Broken Conductor (ANSI 46BC) • Negative sequence voltage (ANSI 47) The FTU is able to report fault event, fault direction and fault clearance event details as time-stamped sequence of events (SOEs). It is also able to save 128 fault events along with corresponding fault direction and associated fault clearance event details upon demand and report to the master.
The FTU support a configurable format for local record reporting including the Comma Separated Variable (CSV) format for use in a spreadsheet and the COMTRADE (IEEE C37.111-1999) format for use with a commercial COMTRADE viewer.

Va/Vab, Vb/Vbc, Vc/Vcb & Ia, Ib, Ic | The connecting terminal on the FTU correspond to the channel number 0~14. For example, the voltage Va of the first power line indicates the voltage at phase A that is define as 0, refers to the signal connecting the first circuit (VT) of the connection board. The current Ia indicates the current at phase A that is define as 6, refers to the signal connecting to the seventh circuit (CT) of the connection board. A Null indicates that there is no signal connected to the terminal. The software configure as Va/Vab, Vb/Vca and Vc/Vcb. The define voltages will display as [Va, Vb, Vc] or [Vab, Vca, Vcb] as per the connection method of star or delta. If non-star or non-delta connection method is select, the voltage input will display as the phase angle of the phase voltage without calculating the power. i.e. Only measurements are available. As for delta connection, 3 connection modes are provided so as to correctively calculate the total power of the power lines and the corresponding equation: P = Vab*Ia + Vcb*Ic = Vba*Ib + Vca*Ic = Vac*Ia + Vbc*Ib, of which the relationship must strictly follow to correspond the input/output of the voltage during connection. When defining, whether interface Vab represents Vab or Vba, interface Vca represents Vca or Vac and interface Vcb represents Vcb or Vbc will determine by the physical connection. From the point of view, voltage |Uab|=|Uba|, |Uca|=|Uac| and |Ucb|=|Ubc| must be determine during connection to calculate power. |

To design for the adjustable of the tap position of regulator by considering the following parameters:- Volage set point : - 95 ~130Vac- Time delay: 10 ~ 180 sec - Bandwidth: ±0.6% to ±6% | To design for adjustable of the tap position of regulator by formula: (∆U ı%ı) / E ı±%ı - (∆U = % of Voltage differential of Load Voltage - E = ± of bandwidth in % unit. |
A. Linear curve: able to control adjust the Tap position of Regulator will be depend of the condition follow these parame-ter: i) Voltage Set point is the voltage level to compare with voltage from PT that RTU read (actual Voltage). It mean that if the actual value is different with the Voltage Level of RTU, it will sent Raise/Lower Command to control the Tap Position of Regulator. The FTU is able to readjust the Voltage Set point between 95-130 Vac by receiving the AO command from master. In case of power loss, FTU will still be able to remember last Voltage set point. ii) Time Delay is the setting time for delay consider the Actual Voltage in case of Actual value not same with voltage level, RTU have to count time during the Actual Voltage difference with Voltage Level. If the voltage has been difference until equal with time setting then RTU will send Raise/Lower command to adjust the Tap position of Regulator. Contractor have to designed for RTU able to change value to Time delay in unit of Second between 10-180 Sec. and RTU shall able to mem-orize last count of Time Delay.(incase RTU lost of DC Supply). iii) Bandwidth = Width of changing Voltage Level (in unit of %) that RTU will not send the control command to Raise/Lower Tap Position of Regulator, ie. Bandwidth = 1% of Voltage level at 110Vac then the bandwidth will be between 108.9 Vac. to 111.1 Vac. Contractor shall designed the RTU to able to adjust the Bandwidth setting value between ± 0.6 until ± 6 % of Voltage Level and RTU shall able to memorize the last setting Bandwidth (in case of RTU lost of DC supply). B. Integrate curve: Characteristic of adjust Tap position of Regulator shall be follow formula in Table 1 only. And will not consider the condition of Linear Curve because in some distribution line, the Voltage level will not stable and some time will higher and lower in the short time then it not able to apply the linear curve in to these condition. If apply the Linear curve in unstable line, it will make the electric user get damaged from this condition. The Integrate curve will work by adjust the Tap position of Regulator until the Voltage level change to the normal with no Time delay. |

This interface shows the AO data that are being written in the event the AO commands are sent from master to FTU.
This interface displays all the real time AC measured values and actual values of one Feeder of a node, including frequency, three-phase current and voltage, zero sequence voltage and current, line voltage, three-phase active and reactive, apparent power, total active & reactive and apparent power, three-phase power factor and phase angle, total power factor and phase angle, active power integral kilowatt-hour, reactive integral watt-hour. If active and reactive integral watt-hour is to be viewed, the integral kilo-watt-hour option should first be selected in the remote metering parameter configuration dialogue box. The AC real time values of Feeders of other nodes can be viewed by select-ing node number and Feeder number of that node.
This dialogue box shows the SOE item queue up to 1000 SOE items can be displayed. When the number of SOE items is less than 1000, the actual number will be displayed. When the number of SOE items is over 1000, the new SOE items will overwrite original ones. When the dialogue box is closed then opened again, all the item records will be cleared, and the system is ready to receive new SOE items. The displayed content includes node number that sends remote signaling deflection, channel number in the node, deflection feature of the remote signaling and remote signaling deflection transmission time.
This interface shows the queue of the latest 512 SOE items. When the number of SOE items is less than 512, the actual number will be displayed. When new SOE items are generated after the interface has been opened, new records will not be added. New SOE items will be displayed only after the interface is closed and then re-opened.
This dialogue box shows whether a certain Feeder of a certain node works normally. If operation of the Feeder is normal, then no remote signaling report will appear in the fault status column, and the received value and processing value in the fault data list column will be zero. If fault occurs in that Feeder, the system will display fault termination time in the termination item of the fault report, and display causes of fault (phase over current, zero sequence over current, or zero sequence over voltage) and the circuitry status caused by the fault (circuit breaker action, breaker locks and grounding fault) in the fault status information column. In addition, the real time phase current and voltage values of one cycle before and after the fault of that Feeder will be displayed in the information column of fault data list. As shown in the picture, the over current start-up value of phase current is set at 6 A and overcurrent occurs in phase A, then the fault information generated under the condition of CB tripping is simulated.
This interface shows the queue of the latest 36 fault current items. When the number of fault current items is less than 36, the actual number will be displayed.
