Problems solved by technology

In practical applications, it is necessary to monitor the total compensation of all arc suppression coils in the entire power supply area, whether it is necessary to adjust the gear of the arc suppression coils, or switch on and off the arc suppression coils. The simulation model of the arc suppression coil is established, and there is no simulation for the grounding system of the arc suppression coil, and there is a lack of training content for the simulation of the arc suppression coil.

Abstract

The invention discloses a simulation implementation method for an arc suppression coil grounding system. According to the method, the content of an arc suppression coil grounding system is added intoa simulation system, a power supply area is established according to a power grid structure and an operation condition, the calculation of arc suppression coil compensation degrees, inductor current and capacitor current of the normal and failure conditions of the power supply area is carried out, the information such as the power supply area, equipment and monitoring amount can be directly displayed to trainees, the simulation of the arc suppression coil grounding system can be achieved, therefore, the training content about an arc suppression coil is provided to a dispatcher, and the function of a ground adjustment simulation system is improved.

Description

technical field [0001] The invention belongs to the technical field of power system simulation, and in particular relates to a method for realizing simulation of an arc suppression coil grounding system. Background technique [0002] The operation mode of the neutral point grounding of the power system is mainly divided into two categories: direct grounding and non-grounding. Generally, the system of 110kV and above adopts the neutral point grounding method, and the system of 66kV and below adopts the neutral point non-grounding method. The grounding of the neutral point through the arc suppressing coil belongs to the non-grounding method. When a single-phase open circuit fault occurs, the inductive current flowing through the arc suppressing coil and the capacitive current flowing through are added to the current flowing through the open circuit grounding point. The phase difference of the current is 180 degrees, and mutual compensation reduces the grounding current, and al...
