Analysis Of Maintenance Strategy Of Self-using Power Supply System And Studies Of Design Scheme In Substations

Station power system as an important basis for substation facilities, this is a reliable work of the substation equipment, the equipment level of health related to the safe and stable operation of the substation and the power grid. In addition, the power consumption of the station power system load device, as part of the line losses, it is directly related to the power and effectiveness of energy-saving targets. Therefore, improving the security of vital economic power system and substation. However, under the current system base station power management system, there are still a range of issues related to the production run substation. Operation and maintenance of existing solutions can not be found in real policy-related health conditions and effective equipment defect inspection equipment, and the lack of specific management and technical energy saving measures, while the system itself but also because there are many problems in the design and have defects. Therefore, the safe operation and energy saving target of station power system operation and maintenance, and research and application design has important significance.Firstly, the existing station for electric system operation and maintenance strategies to analyze the problems and improve the safety and economy in two ways. Using a large load test method, in 148 substation station power system testing, test data are summarized according to the current station power system operation and maintenance aspects of the actual presence of security risks, proposed technical measures to improve the management and impact assessment validation, basically formed a complete security operation and maintenance programs to ensure safe and stable operation of the station’s power system. At the same time, through the station power system load composition and characteristics of the statistical analysis focuses on electricity substation prominent reasons put forward appropriate technical management of energy saving measures in the context of security and stability, the formation can be applied substation power system operation and maintenance of energy saving programs and Guangzhou Power Supply Bureau substation within a range of management confirms the scheme can be implemented and the corresponding application effect, improve economic efficiency substation.Next, the article on the current industry standards and domestic electricity grid company designed the basic principles of station power system are summarized, consider reliability and energy saving critical power needs in the design aspects of the proposed Guangzhou Power Supply Bureau Ltd within on key fundamental principles of a typical substation station power system design, combined with station power system capacity limitations and electricity load characteristics requested by station power system Microgrid access program, choose from the main wiring, energy storage devices, photovoltaic element Select the layout, control strategies and other aspects of power generation forecasting research station power systems for micro-grid access propose a sound technical solutions take full advantage of distributed generation technology benefits, improve power system substation security and economy.
