Modeling method and simulation method for monitoring signals in electric power dispatching simulation training system

Abstract

The invention discloses a modeling method and a simulation method for monitoring signals in an electric power dispatching simulation training system. The modeling method comprises the following steps of: performing data processing on all equipment, faults and monitoring signals in the conventional power grid dispatching system serving as a model to form fault data units and monitoring signal data units which are in one-to-one correspondence to the faults and the monitoring signals; counting, arranging and classifying the fault data units and the monitoring signal data units to form a fault data repository and an unlabelled monitoring signal data repository; matching the monitoring signal data units in the monitoring signal data repository with the fault data units in the fault data repository by using equipment information as the corresponding standard; and marking a trigger label to be searched and screened and the like on each monitoring signal data unit. The modeling method and the simulation method have the advantages that secondary equipment monitoring signals can be effectively simulated, the simulation authenticity and recoverability of power grid monitoring signals are achieved to the greatest extent, and an actual effect of simulation training is greatly improved.

technical field [0001] The invention relates to a modeling method and a simulation method of a simulation training system, in particular to a modeling method and a simulation method of a monitoring signal of a power dispatching simulation training system. Background technique [0002] The power dispatching simulation training system is to cultivate the dispatcher's ability to grasp the overall operation status of the power grid and the ability to respond to and correctly handle power grid emergencies in a timely manner. It is a very important training system. [0003] We know that there are primary equipment and secondary equipment in the power grid system. In a real power grid dispatching system, primary equipment includes lines, buses, loads, generators, transformers, switches, circuit breakers, capacitors, reactors, etc., The monitoring signals generated by these primary equipment failures are relatively easy to simulate, but the secondary equipment monitoring signals ge...

AI Technical Summary

Problems solved by technology

[0003] We know that there are primary equipment and secondary equipment in the power grid system. In a real power grid dispatching system, primary equipment includes lines, buses, loads, generators, transformers, switches, circuit breakers, capacitors, reactors, etc., The monitoring signals generated by these primary equipment failures are relatively easy to simulate, but the secondary equipment monitoring signals generated by secondary equipment such as current transformers and voltage transformers are mainly due to the alarm or alarm generated by the secondary equipment triggered when the primary equipment of the power grid is abnormal or faulty. Action signals and monitoring signals of secondary equipment often cannot be simulated in the true sense in the simulation system

Therefore, in the existing simulation training process, if the monitoring signal of the secondary equipment as an important reference is not simulated correctly or is not real, the fidelity of the dispatcher simulation training will be greatly reduced, which will affect the actual training simulation effect
