摘　　要：我国跨省区电力资源优化配置越来越频繁,然而跨省区联网线路的重要功能之一,即安全功能却一直缺乏合理的费用分摊方法。首先基于输电冗余和潮流跟踪的原理,提出一种确定跨区、跨省联网工程输电成本中联网安全费用成本的方法;然后,提出一种事故紧急支援电力比例方法,来确定联网安全费用在受益各省级电网的分摊,即将各省级电网获得的最大事故紧急支援电力的比例作为安全费用分摊比例;最后,通过2个实际算例验证了该方法的合理性和实用性。The cross-regional and trans-provincial optimized configurations of power resources are frequently adopted in China, however it is still short of a rational method to allocate the cost of an important function, namely the security function, for cross-regional and trans-provincial interconnected transmission lines. Firstly, based on the principles of transmission redundancy and power flow tracing, a method to identify and allocate the cost for interconnection security in the transmission cost of cross-regional and trans-provincial power grid interconnection project is proposed; then a method to calculate the proportion of emergency supporting power is put forward to determine the allocation of interconnection security cost among the beneficial provincial power grids, i.e., the proportions, by which the beneficial provincial power grids obtain maximum emergency supporting power, are taken as the allocation proportions of security cost for these provincial power grids. Rationality and practicality of the proposed method are verified by the results of two actual calculation examples.
