Problems solved by technology

[0006] The above tests can only reflect its immunity under a single form of interference, and cannot reflect the joint influence of the actual electromagnetic environment, so it often happens that all individual tests have passed but problems still occur in the field environment

Embodiment Construction

[0037] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] The invention provides a testing method, which includes a method of combining the intelligent electronic device with surge testing, electrical fast transient burst testing, voltage sag testing and electrostatic testing under power frequency magnetic field immunity testing.

[0039] The power frequency magnetic field test is aimed at the external magnetic field, and the power supply of the intelligent electronic device adopts an intelligent power supply. The intelligent power supply includes a surge generator, an electrical fast transient burst generator, and a voltage sag generator. During testing, the intelligent power supply can be adjusted to one of the three for testing.

[0040] The generator can not only provide the voltage required for the normal operation of the intelligent electronic device, but also provide the cor...

Abstract

The invention provides a transformer station intelligent electronic device multi-source anti-interference characteristic testing method. The testing method comprises a mixed power frequency magnetic field testing method and a mixed radio frequency radiation anti-interference degree testing method. The mixed power frequency magnetic testing method is characterized in that during the power frequency magnetic field test, the surge test and the static test can be carried out; during the power frequency magnetic field test, the electrical fast transient burst test and the static test can be carried out; during the power frequency magnetic field test, the voltage dip test and the static test can be carried out. The mixed radio frequency radiation anti-interference degree testing method is characterized in that during the radio frequency anti-interference degree test, the surge test and the static test can be carried out; during the radio frequency radiation anti-interference degree test, the electrical fast transient burst test and the static test can be carried out; during the radio frequency anti-interference degree test, the voltage dip test and the static test can be carried out. The method provided by the invention is capable of simulating a plurality of interference ways, which are applied to the intelligent electronic devices at the same time, and then the anti-interference degree can be tested, and the acquired testing result can be used to reflect the actual condition, and therefore the credibility and the authority of the anti-interference degree test can be improved greatly.

Description

technical field [0001] The invention relates to a method in the research field of electromagnetic compatibility of an intelligent electronic device in a power system substation, in particular to a method for testing the multi-source immunity characteristic of an intelligent electronic device in a substation. Background technique [0002] In the limited space of high-voltage substations and converter stations, primary equipment such as busbars, high-voltage transformers, circuit breakers, and isolating switches, and secondary equipment such as protection, control, and communication are gathered. It is a typical environment that combines strong and weak electricity. In the electromagnetic environment of substations, primary equipment mainly generates two types of electromagnetic signals: one is steady-state electromagnetic signals, which exist in the form of power frequency voltage, current, electric field, magnetic field and radio interference; the other is transient electroma...
