综合考虑可靠性和经济性的配电终端优化配置研究

Research on the optimal allocation of power distribution terminal with comprehensive consideration of reliability and economy

配电终端的配置数量和位置对配网供电的可靠性和经济性有重要影响,合理配置配电终端有利于推动配电自动化的经济高效建设。为了在保证供电可靠性的前提下,解决因配网盲目配置"三遥"终端而导致配电自动化投资居高不下的问题,介绍了一种综合考虑可靠性和经济性的配电终端优化配置方法。该方法建立了一个以综合费用最低为目标的配电自动化终端优化配置数学模型,并采用隐枚举法进行求解。将该方法应用于一个架空多分段单联络电网实例,结果验证了其正确性和实用性。

The allocation of the number and location in distribution terminal has an important influence on the reliability and economy of distribution network power supply,and the rational allocation of power distribution terminal is conducive to promoting the economic efficiency of distribution automation construction.In order to ensure the reliability of power supply under the premise,and to solve the problem of high investment in distribution automation distribution network configuration for the blind“three-remote”terminal,this paper puts forward a optimal allocation method of power distribution terminal based on comprehensive consideration of reliability and economy.This method established a comprehensive cost minimum as the goal of the optimization mathematical model of distribution automation terminal,and the implicit enumeration method is used to solve the problem.This method is applied to an example of an overhead multi-segmented single contact power grid,and the results show that the method is correct and practical.
