A system for carrying IP hard pipes by power relay service packets

Abstract

The invention relates to a system for carrying IP hard pipe by electric power relay service packet. A system is connected between relay protection device A and relay protection device B through an IPhard pipe communication module, the IP hard pipe communication module classifies the relay protection message according to the level of the relay protection message, exclusively occuplies resources, preferentially schedule and preferentially forward, the transmission of the relay protection message between relay protection equipment A and relay protection equipment B is not affected even when thesoft pipeline is congested, thus alleviating the problems of low equipment life and difficult to guarantee operation reliability caused by delay and jitter of the relay protection equipment to the maximum extent, and improving the operation reliability of the power relay protection service.

Description

technical field [0001] The invention relates to the field of electric power system relay protection, in particular to a system in which electric power relay protection business groups carry IP hard pipes. Background technique [0002] In the power system, the detection of the running status of power equipment is very important. The timely detection and maintenance of power failures play a vital role in the safe and reliable work of the power system. Abnormal conditions are detected to send an alarm signal, or to directly isolate and remove the faulty part. The power relay protection business has high requirements on the communication delay of the power system. Because the system delay is too large, it will affect the quickness of the fault removal of the relay protection device, making the equipment run for too long under high current and low voltage. , resulting in an increase in the damage rate of equipment. At the same time, the inconsistency of communication transmissio...

Problems solved by technology

The power relay protection business has high requirements on the communication delay of the power system. Because the system delay is too large, it will affect the quickness of the fault removal of the relay protection device, making the equipment run for too long under high current and low voltage. , resulting in an increase in the damage rate of equipment, and at the same time, the inconsistency of communication transmission and reception in the power system will also increase the probability of misjudgment of the relay protection device, affecting the reliability of the relay protection business

[0003] The inconsistency of communication paths and network jitter in the power system are the main factors causing the inconsistency of communication transmission and reception delays. At present, no relevant technical personnel have proposed a better solution to reduce the interference of the above two influencing factors on power relay protection equipment, thereby improving power. The solution for the reliability of the relay protection business, so the current power relay protection business has problems such as low equipment life and difficulty in guaranteeing operation reliability due to time delay and jitter
