Abstract: According to the basic theory of electromagnetic compatibility design and characteristic of power plant excitation control system, the new microprocessor excitation control device was designed. This paper analyzed the possible confronted electromagnetic interference problem of its different plug-in units and presented an electromagnetic compatibility solution scheme. The test validation and practical operation show that the anti-interference capability of this microcomputer excitation control device is greatly improved, which provides indemnity for security and stability of generating sets.
Key words: excitation control device; electromagnetic compatibility design; reliability; test validation
