Abstract PLC is a processer connected computer and automatic control and have a lot of advantages。wind turbine in the wind power is very important equipment, wind power control system is the normal work, the direct impact on the production of electricity。 So it is very important to monitor the fan on line。
This paper introduces the application of programmable logic controller (PLC) in wind power generation control system according to the working environment and the operating characteristics of the wind turbine and the main control equipment of PLC;The composition and design of the automatic control system for wind power generation are discussed。Selection and configuration of hardware equipment;The ladder diagram of wind power generation control system is compiled。And briefly introduces the control system composed of PLC and other devices and personal computer network。
The system improves the level of automation management of main fan equipment, effectively ensures the economic and reliable operation of the main fan equipment。
Keywords: wind power control system; PLC; Online monitoring
