Transformer station simulation training system based on mixed digital/analogy simulation technology

Abstract

The invention discloses a transformer station simulation training system based on the mixed digital / analogy simulation technology. The transformer station simulation training system comprises a primary simulation system of an electric power system on the side of trainers and a secondary equipment system of a transformer station on the side of trainees. The primary simulation system of the transformer station is used to simulate running states of primary equipment of the electric power system in normal and failed conditions, and transmit data in normal and failed conditions to the secondary equipment system of the transformer station to drive secondary equipment of the transformer station, the transformer station trainees can monitor entire data of the electric power system through the secondary equipment of the transformer station, and the data reflect the real running states of the primary equipment of the electric power system. The transformer station simulation training system provided by the invention can simulate the running states of a power network, forms a complete real-time closed-loop simulation training scene, and can be used for training transformer station operating personnel on the characteristics of protective equipment in a practical running state, enabling the transformer station operating personnel to practice analyzing and handling power network faults, andtraining the transformer station operating personnel for skill tests.

Description

technical field [0001] The invention relates to a simulation training system of an electric power system, in particular to a substation simulation training system based on digital-analog hybrid simulation technology. technical background [0002] In the training of substation operators, in the past, pure digital simulation technology was usually used to realize detailed simulation of substations and their secondary equipment (referred to as soft simulation), but the complexity of the secondary system is difficult to simulate through soft simulation, and its fidelity is difficult to achieve. The effect is consistent with the real substation. At present, many power training centers have established training rooms with various voltage levels, and purchased various secondary equipment such as protection screens and measurement and control screens. Since there is no power network model, the output of each signal is isolated and one-way, which cannot reflect Due to the dynamic ch...

[0002] In the training of substation operators, in the past, pure digital simulation technology was usually used to realize detailed simulation of substations and their secondary equipment (referred to as soft simulation), but the complexity of the secondary system is difficult to simulate through soft simulation, and its fidelity is difficult to achieve Consistent effect with real substation

At present, many power training centers have established training rooms with various voltage levels, and purchased various secondary equipment such as protection screens and measurement and control screens. Since there is no power network model, the output of each signal is isolated and one-way, which cannot reflect Due to the dynamic characteristics of the current and voltage signals of the substation, various equipment can only be used for separate training, and cannot truly simulate a complete substation operation scenario
