Research of Reactive Power Dynamic Compensation Controller for Oil-field Motor

In order to raise the power factor of distribution system for oil field, the curve of load characteristics of asynchronous electromotor used in oil-field was given by analyzing the measurement data which acquired on the spot at Daqing Oil Field of China in this paper. In view of some existing problems of reactive power compensation, some advantageous methods and techniques to improve power factor based on analyzing the load performance and the operation state were given, according to the basic principle and method of reactive compensation, the function and characteristics of ADmuC812 monolithic integrated circuit, designed a new type of intelligent dynamic reactive power compensation controller for oil-field motor, raised the electric power quantity of the travel-beam pumping unit greatly.
