| Energy conservation is an important task for our economy and society. Effective voltage control and reasonable reactive power compensation is not only to ensure the voltage quality, but also reduce the grid power consumption,and keep the grid stability. This paper analyzed the current situation of Bazhou rural power and built a reactive automatic compensation system. The main work is as follows:(1) Automatic voltage and reactive power system design theory analysis.Describe the system functional requirements, as well as design principles Bazhou rural network reactive automatic compensation. Further according to the actual situation of the grid, the control algorithm is optimized adjustment. Finally, the classic model of the regional power grid simulation shows the necessity of reactive power automatic compensation system design.(2) The design of reactive power automatic compensation system architecture.Combining the existing OPEN-3000 dispatching automation system platform of Bazhou grid, first the overall hardware and software architecture of the grid automatic voltage control system is shown. Secondly, the principle of hierarchical partition space to make reactive power balance regional presence, dispersion and time associated with such issues in the operation are solved. Finally, communication systems, reactive power and voltage control strategy security system have been designed. The design basis for Bazhou rural network reactive automatic compensation system is provided(3) A detailed description of the application and its operating cost Bazhou county-level city grid AVC system.First introduced the characteristics of AVC control system automatically adjust. Next, a description of the status of the implementation of the system set up, reporting program implementation, accident blocked the implementation of the processing, communication systems. Then several of the system functional testing, as well as the actual running test are shown. Finally, f the rural power supply company Bazhou reactive automatic compensation system operation cost is analysis.In this paper, the design and implementation of Bazhou rural power supply company reactive automatic compensation system achieve the reasonable investment of reactive power compensation equipment, and the real-time closed-loop optimization of reactive power and voltage control. Thus further improving the Bazhou dispatching automation level, and the overall quality of the grid voltage. |
