Abstract

The invention provides an implementation method of circuit breaker reclosing of an intelligent substation, and is mainly applied to the intelligent substation of 110kV and above voltage grade. A localbus protection device is utilized, the reclosing function preset in line protection or circuit breaker protection is implemented by the mode of software transplantation and the corresponding GOOSE subscription virtual terminal is added in the model file to implement the reclosing function. With application of the method, the reclosing function of the circuit breaker of the same voltage grade of the whole station can be implemented in an integration way, and the objectives of saving cable investment, reducing the workload of cable construction, enhancing the reliability and enhancing the expandability can be achieved.

Description

technical field

[0001] This method is applicable to busbar local protection devices, which are generally used in intelligent substations with voltage levels of 110kV and above. Background technique

[0002] According to the relevant technical regulations of our country, when the main wiring of substations with a voltage level of 110kV and above adopts a half-wiring mode, the reclosing function is configured in the circuit breaker protection; when the main wiring adopts a double-bus wiring mode, the reclosing function is configured in the line protection.

[0003] In order to finally realize the modularization of secondary equipment for relay protection in smart substations, the local release of secondary equipment for relay protection has been carried out. After the protection device is lowered on the ground, the number of cables used can be greatly saved and the difficulty of laying can be reduced. However, based on the current reclosing configuration method, when no-volta...
