Power Grid Reliability And Analysis Research Program

In recent years, the scale of China’s growing power, and its structure is more complex, it has formed the majority of the main grid and bicyclic ring network operation, the region’s high-voltage power distribution network for the110kV, have all been open-loop operation, and as people aspects of power supply quality and reliability requirements continue to increase, the urgent need to further promote the power construction work, especially in urgent need to solve large-scale power outage protection as a result of factors to improve the safe operation of the power grid from a fundamental level.Wulanchabu protection system focused on the reliability of the grid in this article affect the reliability of the grid. Firstly, a comprehensive analysis of the performance of the grid protection devices, pointing out the actual problems and weaknesses, to clarify the use of new computer protection device in place of the conventional superiority of protective devices, in order to achieve improved reliability and protection devices safe and stable operation of the power grid purposes. Secondly, respectively, from the power system to start several important primary equipment (such as transformers, bus, transmission lines), for each protection principle, configuration, setting value and achieve technically be updating and upgrading the device, effectively solved defects of conventional protective devices, a good safeguard the reliability and stability of the region Wulanchabu grid. Meanwhile, starting from a few other factors that may affect the reliability of the grid, analyze the impact of various factors on system reliability, and its proposed classification and analysis, providing a theoretical basis for assessing the reliability of the system, reliability improvement.
