摘要
针对目前供电企业计算线损率方法过于落后,不能满足降损工作需要这一问题,结合电力系统实际情况,在充分考虑抄表方式、负荷波动、过境电量等影响线损率波动因素的前提下,分别求出低压用户、专变用户、工业大用户的实际售电量,从而得到实际总售电量,再利用传统线损率计算公式求出月度实际线损率。MATLAB仿真结果表明,该方法在实际计算线损率的应用中具有较高的可靠性和精度。
Line loss rate calculation methods currently used by power distribution service providers are outdated and can no longer meet the requirement of line loss calculation needs today. Incorporating the actual power system situations, a quantitative calculation method is proposed. Comprehensive considerations of various factors that can affect the fluctuation in the line loss rate are incorporated into the method. These factors include the meter reading method, load fluctuation, and cross- border electric quantity, etc. The actual electricity consumption for the low tension users, special transformer users, and large industrial users are separately calculated to get the actual total electricity consumption. The monthly actual line loss rate is then obtained by traditional formula for line loss rate calculation. MATLAB simulation results show that the method proposed has higher reliability and precision in the practical applieations for calculating line loss rate. The results might be widely used in guiding the work on power network planning and loss reduction.
