A circuit breaker control method and system based on rsm prediction model

Abstract

The invention discloses a circuit breaker control method and system based on an RSM predictive model. The method includes: analyzing and determining factors affecting heat accumulation / dissipation of a circuit breaker, and obtaining historical data of the influencing factors and corresponding heat accumulation / dissipation Historical estimation data; build the RSM prediction model by fitting the correspondence between the historical data of the influencing factors and the historical estimation data of heat accumulation / dissipation; input the real-time data of the influencing factors of the circuit breaker at different times into the RSM prediction model, and obtain different time points Estimated value of heat accumulation / dissipation; draw real-time heat accumulation / dissipation curves based on estimated values ​​of heat accumulation / dissipation at different times; open and close control of circuit breakers based on real-time heat accumulation / dissipation curves.

Description

technical field [0001] The invention belongs to the technical field of circuit breaker control, and in particular relates to a circuit breaker control method and system based on an RSM predictive model. Background technique [0002] A circuit breaker is a switchgear circuit breaker that can close, carry and break current under normal circuit conditions and close, carry and break current under abnormal circuit conditions within a specified time. It can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, etc., and can automatically cut off the circuit when they are seriously overloaded or short-circuited or under-voltage. Its function is equivalent to a fuse-type switch and overvoltage Combinations of underheating relays, etc. Moreover, there is generally no need to change parts after breaking the fault current. In order to prevent the circuit breaker or motor from being repeatedly or periodically overloaded and burn...
