On-line monitoring system and method of artificial intelligent high-voltage circuit breaker

Abstract

The invention discloses an on-line monitoring system and method of an artificial intelligent high-voltage circuit breaker. The system is used for acquiring real-time data and non-real time data of a substation and monitoring technical indexes such as mechanical property, control loop characteristic and warning signal characteristic of the high-voltage circuit breaker in an on-line way, the monitoring time parameter accuracy is not larger than 1 millisecond, the accuracy conforms to a circuit breaker manufacturing parameter range, and a delay error of a control loop comprising different physical links also can be compensated by an artificial intelligent technology. The monitoring range of the system is expanded to control loop and warning signal from equipment body, and the system has the advantages of installation and debugging without power failure, no trigger on equipment and control loop, no electromagnetic interference, no addition of extra operation and maintenance workload and the like. The on-line monitoring system of the artificial intelligent high-voltage circuit breaker and power-failure prevention experiment form a power-failure artificial experiment and on-line intelligent monitoring dual-functional active early-warning guarantee system, and a decision-making reference is provided for optimization of the circuit breaker running and maintenance strategy.

Description

technical field [0001] The invention relates to the field of smart grid monitoring of power systems, in particular to an artificial intelligence high-voltage circuit breaker online monitoring system and method. Background technique [0002] A high-voltage circuit breaker is a special electrical appliance that connects or disconnects a high-voltage circuit under normal or fault conditions, and is the most important safety protection device for the power grid. Compared with static transformers, reactors, capacitors and other electrical equipment, high-voltage circuit breakers must ensure correct action during frequent normal opening and closing and fault-cutting, and their opening and closing times and their different timings are insulated from electrical equipment. Factors such as overvoltage, synchronous paralleling of equipment, and damage to the dynamic and static contacts of circuit breakers are closely related. Therefore, online monitoring of the opening and closing char...

Problems solved by technology

Obviously, the external sensor solution currently has at least the following deficiencies: the sensor is expensive and has doubts about its reliability; it brings about sensor inspection problems and increased maintenance workload; the installation space is large, and the product size does not match the actual engineering installation. ; Fiber optic signal extraction and anti-interference and electromagnetic problems; there are interference factors such as temperature, vibration and external magnetic field; incomplete type test reports for components, etc.

This solution has just started, and currently there are still some shortcomings such as few business scenarios and technical models, insufficient monitoring parameter dimensions, and low level of intelligent analysis.
