摘要 提出了一种输电系统网损分摊方法,这种方法以网络稀疏的导纳矩阵为基础,指出在输电系统中进行功率交换者都应该是网损的承担者,各功率交换者应承担网损的份额与其在网络中的地点和交易量有关,将网损应合理分摊给功率交换者。这种方法与其他方法相比的突出优点是以潮流解为基础,容易理解和执行。它虽应用了网络等式但不需要任何假设,各功率交换者应承担网损的份额主要取决于网络导纳矩阵的实部及节点电压。给出了示例系统的计算结果并与其他方法的结果相比较,表明所提方法的合理性。 A procedure based on network admittance matrix for allocating transmission losses is presented.It is suggested that all participants of power trade in power transmission system have to share the power losses.The loss allocated to each participant is related to the location and the trade amount.Unlike other approaches,it exploits whole set of network equations and does not require any simplifying assumption.The solved load flow is used as its basis,which is easily understood and implemented.The loss allocation applies the bus voltages and the real part of the admittance matrix.The calculation results for an example system are given and compared with the results by other methods,which illustrates its rationality.
