3 Theory of Protection

3 Theory of Protection
3.1 Software architecture Figure 3.1 shows the outline of the software

Figure 3.1 Software flow block Protection software includes main process, interrupt process and routine process and fault process. Main process achieves tasks such as hardware self-check, mutual-check between HMI module and CPU module, settings check, and performing interrupt process periodically. Hardware check involves ROM, RAM, EEPROM and OUTPUT. In interrupt process, analogy input sampling and filtering, digital input sampling, startup element calculation is performed. If relay starts, the program entries into fault process, otherwise, into routine process. When startup element reset, the program returns to routine process. Routine process involves samples offset supervision, status supervision (including TA supervision, CB status). Serious alarm latch the relay and causing the relay out of service; general alarms just issue signals do not latch the relay. Fault process involves CB failure startup, 3-phase disaccord protection, charge protection and overcurrent protection. Additionally, events, disturbance, and internal elements status are recorded. 3.2 Charge protection Charge protection is automatically enabled in 10 seconds only as manual closing

3 Theory of Protection

(GUARANTEE: Charge protection is off as relay is reclosing). Charge protection is automatically off after 10 seconds. Charge protection will drive the relay CDJ. See to Figure 3.2 (upside). The relay don’t need special “manual closing” signal. Manual closing status is judged completely by breaker state: 3 phases breaker is open and no current (<0.04In), this status holds more than 30 seconds. 3 phases breaker isn’t open or current exists after the status, relay judges “manual closing”.

Figure 3.2 Charge protection scheme Charge protection function is chosen on or off by bit 5 of control word. It is the O/C protection, which has time delay and not direction. As any phase current over charge protection current setting at manual closing, the relay will trip through charge protection time delay. The relay reset automatically after charge protection is enabled in 10 seconds. 3.3 Overcurrent protection (O/C protection) The relay has one zone O/C protection, which meets user’s need. “O/C protection switch” control it’s on or off. See to Figure 3.2 (underside). The relay has indication light in front panel, which prevents long term on. Also two couples signal contacts of signal module indicate O/C protection switch status (The contact is close when O/C protection switch is on). O/C current setting distinguishes from charge protection setting completely.

3 Theory of Protection

3.4 3-phase disaccord protection The relay can distinguish single phase disconnect and two phases disconnect because split phase state connects of breaker is input. Time setting of 3-phase disaccord need over single phase reclosing time as disaccord breaker is caused by single phase breaker disconnect, because single phase reclosing latch connect don’t input. Time delay is set 0.5 second changelessly as disaccord breaker is caused by two phases breaker disconnect. 3-phase disaccord protection can choose zero-sequence current latch to improve reliability by bit 12 of control word. 3-phase disaccord protection function is chosen on or off by bit 13 of control word. See to Figure 3.4.

Figure 3.4 3-phase disaccord protection scheme Note: Non-all-phase protection of 3-phase disaccord relay is chosen on or off by bit 7 of control word if breaker offers “3 phases disaccord” DI contact. The relay trips through

3 Theory of Protection

3-phase disaccord time setting as “3 phases disaccord” DI inputs. Relay will reset if “3 phases disaccord” DI disappears and delay time isn’t up to setting. 3.5 CB failure startup CB failure startup can retrip local breaker by bit 8 of control word. Logic of CB failure startup is achieved by software. So it doesn’t need external contact. The relay offers two couples contacts of CB failure startup. The relay simulate phase A, B, C current (LJA, LJB, LJC) and 3-phase current (LJ3). It adopts contacts of protection trip failure startup output and phase current relay in series according to phase. See to Figure 3.5-1. TJA TJB TJC TJQ

Phase current relay contactor CB failure startup contactor

Figure 3.5-1 CB failure startup connect scheme The relay adopts two measures to improve reliability of CB failure startup: ⑴ The CB failure startup element use two startup element to offer the power supply of CB failure startup relay. ⑵ It use two couples contacts of two disparate relay to output in series from one couple contact ineffective. 3.5.1 Superimpose element ⑴ Superimpose startup’s criterion:

?i? =| i? (t ) ? 2i? (t ? T ) + i? (t ? 2T ) | ?i? > ?I ZD + 1.25?I T
Where: ? is a, b, c, T=20ms, ?Izd is setting, ?I T is superimpose last cycle. ⑵ When any current superimpose is greater continuously than the threshold 3 times,

element operates. 3.5.2 Zero sequence current startup element To avoid the sensitivity of zero sequent O/C zone Ⅳ is more than superimpose startup, which maybe cause zero sequent O/C zone Ⅳ operates, otherwise CB failure can’t startup. A zero sequent current element is applied. It is suggested that this element setting should be more sensitive than corresponding setting of line protection. Either zero sequence current or superimposed element startup, the program will entry fault process. After startup element startup, the contacts of CB failure startup operate
immediately as any phase current is over setting of CB failure startup and corresponding phase

trip DI inputs, which is applied in startup busbar failure startup. After the contacts of CB failure startup operate, they will return if current is less than setting or trip DI inputs disappears. CB failure startup is chosen on or off by bit 9 of control word. See to Figure 3.5-2.

3.6 Alarm circuit

3.6.1 Self check The relay checks whole system of itself, include ROM, DI and DO. It will give corresponding report and give out alarm signal if hardware arises error. 3.6.2 DI check It reports “abnormal trip state” and gives out call signal if trip state DI and corresponding phase current both exist 3 seconds continuously as the relay doesn’t startup. It reports “abnormal disaccord” and gives out call signal if disaccord state is judged by the relay or 3-phase disaccord DI operates as zero-sequence current is less than 3-phase disaccord zero-sequence current setting, which holds 5 seconds continuously, when 3-phase disaccord protection is on and latched by zero-sequence current. It reports “abnormal disaccord” and gives out call signal if disaccord special DI operates and current exists in 3-phase, which latches 3-phase disaccord protection trip and holds 5 seconds continuously, when 3-phase disaccord protection is on and not latched by zero-sequence current, disaccord uses special DI. It reports “abnormal trip DI” and latches CB failure startup if trip output holds 60 seconds continuously. It reports “abnormal trip DI out” as trip output returns. 3.7 AC circuit abnormal criterion The relay checks phase sequence of current when it has been power on in two hours. It’s criterion:
⑴ ⑵

3I 2 > 0.25 I n ; 3 I 2 > 4 × 3I 1 ;

⑶ hold 1 minute continuously;

Above-mentioned criterion is all met, it reports “TA inverse sequence” and gives out call signal, not latches protection. It reports “Load asymmetry” and gives out call signal, not latches protection,
11

3 Theory of Protection

when maximum difference of inter-phase current is greater than a half of maximum phase current and maximum phase current is greater than a quarter of rated current, which holds 10 minutes continuously. It reports “TA unbalance” when zero-sequence current 3I 0 is greater than zero-sequence current startup setting, which holds 10 seconds continuously. The relay will come back normal status in 1 second after zero-sequence current returns. 3.8 Events records and analysis PSL 631A provides disturbance records. The available analogue signals consist of Ia,Ib,Ic,3I0. The available state signals include auxiliary contacts of CB, trip outputs. For convenience of analysis, the derived 3U0 is also recorded. Up to 12 to 48, generally 30, disturbance records are stored, Up to 1000 event records are stored. The reports or events can be extracting by PC. In PSL631A, disturbance record, events settings and internal flags can be read out by PSView software. PSView can read out the events sent from relay online and extract history records. 3.9 Integrated with automation system PSL631A could be integrated with automation system or non-automation system. All protection function can be configurable via key-panel or communication system from remote. 3.10 Print and display PSL631A Protection events table:

5. 2 PSL 631A breaker protection setting guide All settings have four valid digits, so most three digits behind pot, for example, 1.234. Setting step is 0.01A for current and 0.001second for time. 1) “Su-chg-val.start ” This setting is used as fault detector, which will enable the protection of CB failure protection when the currents raise enough. 2) “Z-s.cur.start” This setting is used as earth fault or TA disconnect detector, which should be set more sensitive than setting of the zero-sequence current zone Ⅳ to ensure that CB failure can startup when zero-sequence current zone Ⅳ trip . 3) “fail.star. cur.” It is applied in judging the breaker trip or not as fault. Its principle is: ⑴ Be sure the sensitivity for the fault at end of local line, sensitive coefficient is over 1.3. ⑵ Should avoid capacitive current of line. 4) “Charg.prot.cur.” Its principle is: ⑴ Be sure the sensitivity for the fault at end of local line, sensitive coefficient is over 1.3. ⑵ Should avoid the load current of line. 5) “O/C prot cur.”

Its principle is: ⑴ Be sure the sensitivity for the fault at end of local line, sensitive coefficient is over 1.3. ⑵ Should avoid the load current of line. 6) “3-p-disac. Z-s” The setting is the threshold of zero-sequence latching current. If zero-sequence
current doesn’t latch 3-phase disaccord protection, the setting is ineffective.

⑴ Avoid the unbalanced zero-sequence current of line. ⑵ Be sure the sensitivity of non-all-phase operating. 5.3 Switch settings Need config item: ⑴ Relay chooses function switch mode (soft switch or hard switch), which is on or off. ⑵ Setting of relay and setting zone. ⑶ Transmission line name.
