Redundant processor unit PM862K02

 

Application To achieve fast fault clearing for a fault on the part of the line not covered by the instantaneous zone1, the stepped distance protection function can be supported with logic that uses communication channels.

For the Phase segregated scheme communication logic for distance protection (ZC1PPSCH) three channels in each direction, which can transmit an on/off signal is required. The performance and security of this function is directly related to the transmission channels speed, and security against false or lost signals. Special communication channels are used for this purpose. When power line carrier is used for communication, these special channels are strongly recommended due to the communication disturbance caused by the primary fault.

Communication speed, or minimum time delay, is always of utmost importance because the purpose for using communication is to improve the total tripping speed of the scheme. To avoid false signals that could cause false tripping, it is necessary to pay attention to the security of the communication channel.

At the same time, it is important pay attention to the communication channel dependability to ensure that proper signals are communicated during power system faults, the time during which the protection schemes must perform their tasks flawlessly.
