Abstract：with the vigorous development of modern science and technology, the production technology of thermal power plant is gradually maturing. Green and efficient new science and technology is the development direction of modern power enterprises. The use of high voltage inverter in thermal power plants has achieved great economic benefits after many years of development practice. In the process also accumulated a lot of experience, gradually tend to mature, but the use of high-voltage inverter in thermal power plants belongs to high-tech equipment. There are still many hidden dangers in the domestic production management conditions. This paper expounds the defects of the high voltage frequency converter, the equipment operating environment and the equipment control system, etc.The problems often appear in the operation of high voltage inverter in thermal power plant are analyzed, and some suggestions for improvement are given.
Key Words：high voltage converter; thermal power generation; operation problem; frequency conversion transformation
