To construct a supervisory control platform for hybrid energy supplement power supply system, the constitution, functions of a power management system are proposed. Supervision and control system is founded based on KingView according to functional requirements and characteristic s of the power management system. Driving procedure of the KingView is written according to communication protocol of the data acquisition module at first Communication between PC and machine is achieved. Then, the running of equipments is simulated, and real-time date is monitored, showed, analyzed and processed. Then optimal management, coordinative control and seamless switching of hybrid energy supplement power supply system are achieved.

Based on traditional complementary power supply system, the actual wind-PV-diesel hybrid energy supply system comprising three energy sources, namely PV, wind and diesel generations based on dc bus is established. Each of the three energy sources is controlled so as to deliver energy at optimum efficiency. Then the designing and computing modeling of distributed sources such as wind turbines, photovoltaic array and battery is proposed. Models of wind turbines, photovoltaic array and characteristics of the battery, respectively established the mathematical model of them, and then the simulation model is respectively built by PSCAD/EMTDC. So a micro-network experiment and simulation platform is established, which can simulate any power of wind and solar power output characteristics.

The wind power generation pumping unit has environmental protection and the energy-saving function with wind power generation complementary power supply system. Based on the calculation of the pumping power consumption during the oil production, the essential wind-power generation electric quantity for pumping equipment runs stable was analyzed, wind-electricity and electric network complementary energy transmission and control circuit were designed, When the wind speed changes, by the energy transmission and control circuit related parameters and taking the historical meteorological statistics of the corresponding period as the comparison reference, the system can control wind power generation and the battery charge and discharge flexibly to ensure the equipment runs stable, which lays a firm foundation for the wide application of the off-grid wind power. The economic analysis shows that the wind-electricity and electric network complementary pumping machine has good economic efficiency and application prospect in oilfield.
