Abstract

The invention provides an electromagnetic field test platform for simulating power grid event disturbance. The electromagnetic field test platform comprises a power supply module, a comprehensive control and display module, a phase control module, a power frequency electric field generation module, a power frequency magnetic field generation module, an impact magnetic field generation module and awaveform measurement module, the power supply module provides a high-power power supply for the simulation generation platform; the comprehensive control and display module controls generation of a power frequency electric field, a power frequency magnetic field and an impact magnetic field and displays parameters such as an output voltage value, a current value and a phase in a centralized manner; the phase control module controls the impact magnetic field generation module to output an impact magnetic field, a power frequency magnetic field and a power frequency electromagnetic field to output at any superimposed phase; and the waveform measurement module realizes synchronous measurement of power frequency high voltage, power frequency current and impulse current waveforms. According tothe invention, simultaneous output of a power frequency electric field, a power frequency magnetic field and an impact magnetic field can be simulated, the impact magnetic field and the power frequency electromagnetic field can be superposed at any phase, and the electromagnetic field environment requirement of an online monitoring device or a live detection instrument during laboratory calibration is met.

Description

technical field [0001] The invention relates to the technical field of detection and calibration of electrical equipment state detection instruments, in particular to an electromagnetic field test platform for simulating event disturbances in power grids. Background technique [0002] There are power frequency electric fields, power frequency magnetic fields, impact interference, radio interference, noise interference, etc. in the transmission lines and substations in operation. At present, a large number of live detection instruments are used to detect the operating parameters of electrical equipment in the live state, and are very vulnerable to various electromagnetic interferences during use, resulting in data instability and other problems; and the online monitoring devices widely installed in substations. Operating in a complex electromagnetic environment, its performance will be reduced or even lost, and it will not be able to exert its due monitoring and early warning...
