An intelligent circuit breaker control system based on iec‑61850 standard

Abstract

The invention discloses an intelligent circuit breaker control system based on IEC (international electrotechnical commission)-61850 standards, and belongs to the field of power control and power protection. The intelligent circuit breaker control system comprises a main control panel and an input and output power supply board, wherein the main control panel comprises an MMS processor, a protection task processor, a GOOSE / SMV processor, an analog acquisition unit and a communication unit, realizes the analog acquisition, and protects the test and control function logical operation, and the input and output power supply board comprises an IO processor, an input quantity input unit, an output quantity output unit and a power supply module, and realizes circuit breaker position signal and handcart stroke switch position signal collection and circuit breaker divide-shut brake output control. The intelligent circuit breaker control system is arranged inside a circuit breaker case, so that the circuit breaker becomes an intelligent circuit breaker integrating on-off operation, measurement, protection, control and communication.

Description

technical field [0001] The invention belongs to the fields of power control and power protection, and in particular relates to a circuit breaker control system. Background technique [0002] At present, medium and low voltage circuit breakers are widely used to protect the overhead distribution network, cable feeders and distribution substation systems. In addition to the normal switching of the rated current of the system, the circuit breaker is also required to quickly cut off the short-circuit fault current of the system when the system fails, and has Quick action and selectivity, and no leapfrog tripping phenomenon. [0003] With the intelligent development of power system control technology, the intelligence of many circuit breaker protection equipment is getting higher and higher, but it is separated from the circuit breaker after all, and it is a kind of intelligent secondary equipment; there are few intelligent equipment and circuit breakers. The two mechanisms are ...

Problems solved by technology

[0003] With the intelligent development of power system control technology, the intelligence of many circuit breaker protection equipment is getting higher and higher, but it is separated from the circuit breaker after all, and it is a kind of intelligent secondary equipment; there are few intelligent equipment and circuit breakers. Combining two mechanisms into one makes the circuit breaker itself intelligent
