An electromagnetic disturbance simulation test platform for the secondary system of a substation

Abstract

The invention discloses an electromagnetic disturbance simulation test platform of a transformer substation secondary system, and belongs to the technical field of electromagnetic compatibility of transformer substation secondary equipment. A first electromagnetic disturbance measuring system, a first simulation sensor, a basin-type insulator and a second simulation sensor of the electromagnetic disturbance simulation test platform are distributed at the different positions on a GIS pipeline outer shell, and the GIS pipeline outer shell is connected with an outer shell of a simulation remittance control component cabinet through a plastic coated metal hose. A secondary cable of the first simulation sensor and a secondary cable of the second simulation sensor penetrate through the plastic coated metal hose to be connected with the electromagnetic disturbance measuring system. According to the electromagnetic disturbance simulation test platform, the actual transient state electromagnetic environment of a transformer substation can be simulated conveniently and truly, and electromagnetic disturbance caused by different sources is researched; meanwhile the electromagnetic disturbance suffered by the secondary system under different loads and different grounding modes can be studied comprehensively.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic compatibility of substation secondary equipment, and in particular relates to an electromagnetic disturbance simulation test platform of a substation secondary system. Background technique [0002] Short-circuit faults, lightning strikes and switching operations in substations will generate different degrees of electromagnetic disturbance to the secondary system, which poses a great threat to the safe operation of the secondary system of the substation. Because it is very difficult to carry out short-circuit fault, lightning impulse and switch operation tests in the actual substation, and the number of tests is also limited, so building a test platform is an effective way to solve the problem. From a research point of view, the impact of different grounding methods and different load levels on the secondary system is not yet clear. It is necessary to carry out experimental research to find...
