Research On Construction And Operation Performance Of Automatic Voltage Control Of Yizhuang Grid

In recent years, with the rapid development of economic and construction in YiZhuang, the grid is becoming more and more complex.The proposed grid voltage control methods are facing some new problems.They cannot meet the regional power grid running for safety, quality and economic requirements.In this thesis, the YiZhuang grid automatic voltage control system (the automatic voltage control, AVC), from a global point of the grid, automatic all optimizes the control of reactive power and grid voltage.The control system effectively reduces the net loss of the system, improves the grid voltage pass rate, and reduces the intensity of the work of the operating personnel.In this paper, the application of project management theory, combined with the characteristics of information technology project management, the construction and application of automatic voltage control information project of Yizhuang power supply company is analyzed. First, the status of understanding Yizhuang power supply, voltage control based on the analysis of automatic voltage control of the design and development of informatization project economic feasibility, the feasibility of the management, social feasibility and technical feasibility, and analysis the demand of the project. Next, to automatic voltage control function of information project implementation as the ultimate goal, the construction of the project for the whole process of management, starting from the project management, the determination of the organizational structure of the project, strict control of the project cost, quality, and strengthen the project allocation, risk, change management, prudent in selecting suitable project operation mode and project delivery methods, Yizhuang power supply company automatic voltage control the construction of project information.Based on the utilization of AVC in YiZhuang, the automatic voltage control (AVC) system makes full use of dispatching automation system to serve the power system. The evaluation model of Grey Hierarchy Method is established to evaluate the performance of the system.
