摘　　要：为克服近似估算方法计算线损时与实际线损相差较大、缺乏实时性、使得线损分析和理论计算受到限制的缺点,利用SCADA系统的实时数据,在线分别生成基于潮流的电网线损值和基于状态估计的电网线损值实时数据,将实时数据用于理论线损计算,可有效提高线损计算的实时性、结果的可靠性和管理的方便性。To overcome the disadvantages of that theoretical line loss calculating result was greater different from the real value. A method is proposed which the SCADA real-time data were used into theoretical line loss calculation based on power flow and state estimation. This method can effectively improve the real-time of calculation, reliability of result and convenience of management.
