Research on risk control system in regional power grid

Abstract

Today's society increasingly high demand on the supply level of service, and quality service based on the safe and stable operation of power grids, regional power grid face the majority of users directly, while the active power itself can be modulated by a relatively small grid operation security risk is always there, in order to effectively control the risk of grid when it runs and improve ability to resist risks, therefor it is very important to build the system of risk control system of regional power grid. Based on the characteristics of regional power grid itself, described the contents of the regional power grid risks tube control system's design principle, the system software and hardware architecture, which is mainly introduced the regional power grid risk management and control systems: historical data read, grid risk identification and assessment, grid risk comprehensive assessment, grid risk controlling and decision-making, intelligent early warning function, and realize the function of this five respects the need to study the content and technical policy. Regional power grid can effectively analyse, induce and recognise the various potential or inherent risk factors in the regional grid security and stability through the establishment of risk management and control system. at the same time the probability of occurrence of various risk factors and the severity of the impact on the regional power grid are quantified, with the formation of different risk indicators and unified the various indicators of risk, it determines the level of risk ultimately, power companies establish appropriate contingency plans and emergency response programs according to the level of risk, which reduce the risk of the grid operation and improve the supply service levels and the enterprise economic efficiency.
