With the constant development and improvement of frequency conversion technology, its excellent power-saving performance, good start-up characteristics and various protection functions have been better reflected in enterprises, making enterprises to save energy and reduce costs, increased security guarantees. 1. The characteristics of frequency converter frequency control is the performance and development prospects of speed control technology. Frequency converter is the main product used in three-phase asynchronous motor speed regulation in industry development. Its main advantages are: good energy-saving effect, up to 55% ; wide speed regulation range, speed regulation ratio up to 20:1; good start and braking performance, soft start, automatic smooth acceleration and deceleration and rapid braking; perfect protection function, it can realize over-voltage, under-voltage, overload, over-current, instantaneous power failure, short circuit, stall and so on. It can also realize fault diagnosis and display. It is easy to use in computer system and can realize remote control. 2. The application of frequency control technology in the control of cogeneration system 2.1 the central heat exchange station and the external network control boiler system mainly includes the system constant pressure water supply, system hot water (carrier) circulation, system combustion control and furnace pressure control, in the cogeneration, the superheated steam can be directly exported, or it can be exported hot water after steam-water exchange. The heat energy of steam or hot water can be provided to each heat user through the heat exchange stations in the pipe network.
