Transformer Protection Relay , SID - 2CM Automatic Quasi - Synchronizing Device
1 There are twelve channels to be used for 1-12 units power generator or
power lines paralleling in a device, type and attribute of paralleling can be distinguished.
2 Setting parameters: breaker time; Allowable voltage differential; over voltage protecting value;
Allowable frequency difference value; frequency control coefficient; voltage control coefficient;
Allowable power angleIncomer and busbar TV rated voltage; shift busbar TV phase angle;
low voltage lock values on both sides of paralleling point; single side or both sides no-voltage operatingsynchroscope funtion; Control pulse width for same frequence;breaker name .
3 The device can ensure the first zero phase differential appearing to be seized while differential paralleling
(between generator and busbar or two synchronous lines.) and make paralleling without impacting;
4 The device can make a fast paralleling of generators through the way it can leads frequency differential and
voltage differential into the Allowable range according to the theory of fuzzy control;
5 When paralleling will begin at once only if the power angle and the voltage difference are less than the
allowable values when paralleling between synchronous lines, otherwise , there must be a wait and signal,
whether it was differential frequency or identical frequency can be distinguished by the device automatically;
6 The device can make self-test when running timely and automatically, it can also alarm and display if error;
7 Alarming when TV open-circuit and locking the operation of synchronizing and non-voltage closing;
8 An acceleration control instruction can be given automatically when frequency is identical during the
process of paralleling of generators in order to cancel the identical frequency condition.
Paralleling of anti-power will be never appeared surely if necessary;
9 The device will display these data – real measuring time a breaker circuit takes when closing and the
last eight real measuring values recorded in every channel after accomplishing the paralleling in
order to make certain the accuracy of the time it takes when breaker closing.
The time for breakers’ closing will not be recorded when it is identical frequency paralleling.
10 Communication accesses and communication agreements will be provided between the device
and the host computer (RS-232, RS-485), in order to meet the requirements the device will be admitted into the DCS system.
11 The device can work even though under an awful conditions owing its methods of complete
and strict insulation ways on electromagnet and photo electricity;
