Protection functions

1.1 HS/LS OC protection (For MODEL 1)

Both HS and LS OC protections can be selected as instantaneous or definitetime delayed protection according to the time delay setting. If the time settingis zero, it will be working as instantaneous over current protection. Otherwiseit will be definite time delayed over current protection.

These two protections can be configured as forward directional, reversedirectional or non-directional. And the non-directional element will block theforward and the reverse elements. Characteristic angle of directional elementis selectable, 30° or 45°. These two directional over current protections are allblocked by VT fail.

Directional element adopts 90o connection (shown as Tab.1), and it takeseffect to A, B, C phase respectively. The directional arrangement of U/I isshown in Fig.2. To avoid dead zone when voltage is too low to determinedirection, directional element takes the memory voltage .

1.8 U/F&O/F protection (For MODEL 2)

When network frequency is abnormal, under frequency or over frequency, thisprotection will result in tripping after predetermined time. It has 7 stages, andevery stage can be selected as under frequency or over frequency protection.Stage 1 to stage 3 are “f or df/dt”, it means every stage (from 1 to 3) whenfrequency is less than setting or frequency negative change rate is greaterthan df/dt setting the equipment will give DO contacts, if you select underfrequency. And when you select over frequency, the conditions for tripping isfrequency is greater than setting or frequency positive change rate is greaterthan df/dt setting. For these three stages, the df/dt function can be ON or OFF.If df/dt is OFF, this stage is a simple under frequency or over frequencyprotection.

From stage 4 to stage 7, the protection function is written as “f & df/dt”. Inthese stages the df/dt is fixedly ON and the trip condition is that frequency isless than setting and frequency negative change rate is greater than settingwhen under frequency is selected. The trip condition for over frequency


-21-

protection is that frequency is greater than setting and frequency positivechange rate is greater than setting. There are two elements to block thisprotection: VT fail and the minimum phase to phase voltage is less thansetting. The “f + df/dt” logic is showed in Fig 9 and “f & df/dt” is showed in Fig10.

1.10 Over flux (For model 1a)

The over flux protection is used to detect impermissible over flux conditions

which can endanger transformers. The over flux protection must pick up when

the induction admissible for the protected transformers is exceeded. The

transformer is endangered, for example, if the power station block is

disconnected from the system for full-load and if the voltage regulator either

does not operate or does not operate sufficiently fast to control the associated

voltage rise. Similarly, decrease in frequency, e.g. in island system, can

endanger the transformer because of increased induction.

An increase in induction above the rated values leads very quickly to

saturation of the iron core and large eddy current losses. The over flux

protection feature serves to measure the voltage/frequency ratio which is

proportional to the B induction and puts it in relation to the BN nominal

induction. In this context, both voltage and frequency are related to nominal

values of the transformer to be protected.

The over flux protection feature includes two staged characteristics and one

thermal characteristic for an approximate modeling of the heating which the

over flux may cause to the protected transformer. The inverse characteristic

can be set via thirteen points derived from the manufacturer data. In addition,

1.11 VT supervision (For model 1, 1a and 2)

Voltage transformer supervision can supervise bus voltage and report single-phase broken, two-phase broken and three-phase broken if any of thefollowing conditions is satisfied for 9 seconds, CSC-211 will report the alarmof ‘VT FAIL’.

� Self-generated zero sequence voltage and three-phase voltage are allless than 8V and any phase current is more than 0.125A (considered asno-voltage, only for model 1);

� Self-generated zero sequence voltage is more than 8V and minimumphase-to-phase voltage is less than 16V (considered as two-phasebroken);

� Self-generated zero sequence voltage is more than 8V and the differencebetween maximum phase-to-phase voltage and minimum phase-to-phasevoltage is more than 16V (considered as single-phase broken).

For the directional protection, the perfect bus-voltage is significant for theiroperation. Therefore, VT fail will block the protection with directional elements,under voltage and frequency.

9 Diagnostics

Automatic tests including power-on diagnostics and continuous self-monitoring, ensure a high degree of reliability. When any abnormal status isdetected, the alarm indicators and related relay are driven and the dependentevents could be recorded immediately. For some fatal faults, the relay couldbe blocked to avoid the unwanted operation. The results of the self-testfunctions are stored in non-volatile memory.

The virtual test function is provided for the automatic tests of the substationautomation system. The function contains automatic counter point of digitalinput, automatic triggering of SOE.

Test features available on the user interface provide examination of inputquantities, states of the digital inputs and relay outputs. A local monitor portprovides digital outputs, selected from a prescribed list of signals, includingthe status of protection element and may be used in conjunction with testequipment. These test signals can also be viewed using the communicationports and the front panel user interface.
