【摘要】 为了适应负荷实测和线损理论计算对数据的同时性、准确性的要求,提出一种利用状态估计数据进行35kV及以上供电网电能损耗率的计算方法。在分析采用状态估计数据的可能性与必要性的基础上,根据电网线损理论计算软件的计算原理,论述了在状态估计数据中提取电网线损理论计算需要的数据,进行数据转换的步骤和方法。应用结果表明:采用实时数据进行电网线损理论计算,减少不必要的人为错误,提高了效率及计算的准确性和精度。
【Abstract】 For assuring synchronicity and veracity of data that is necessary for load testing and theory calculation of line losses,this paper recommends a means to calculate power line losses of 35kV and above,which uses data of the power state estimation.This paper studies the possibility and essentiality of the state estimation data,and base d on the mathematical model of calculating software for power network line losses,the steps that the data needed by calcula tion is ac quired from state estimation are discussed.The flow-checking ensures that the condition of calculation is same as the actual operation planning.The results indicate:the calculation of line losses with real-time data will decrease the man-made mistakes and increase efficiency,at the same time,the veracity and the precision will be im proved.
