Research On The Reliability Of Operation And Maintenance Of Power Network

With the expanding of the scale and capacity of power network, the reliable and economical operation has exerted a deeply influence on the national economy. At the same time of developing the reliability of normal operation, the research of the maintenance of transmission system has become more and more important.The software researches on the reliability of both normal operation and maintenance of transmission system. The reliability of normal operation of power network is evaluated with quantified indices by analyzing the real-time data of power network and making use of probabilistic simulation method. The software could analyze the operation risk indices of day-mode maintenance and month-mode maintenance with different time section .It could also evaluate the rationality of different maintenance scheme to search the bottle neck in power network and to monitor the key section and find out effective measure to deduce the risk of operation and maintenance in transmission system.Because of different ways of calling the software, it has three different editions: stand-alone edition, multimachine edition, network edition , in order to make the operation of the dispatcher more convenient. With friendly and convenient interface the software has been tested in the IEEE test system and Anhui power network and has been proved to be reasonable and stable. It offers an efficient way to analyze the reliability of normal operation of power network and arrange the maintenance scheme reasonably.
