双比值法在线损计算分析系统的应用研究
|
摘要
线损率是供电企业的一项主要的综合性技术经济指标,体现了电力企业在电网规划设计、生产技术、经营管理等方面的综合水平。本文在理论线损和统计线损计算的基础上采取基于多要素的双比值分析,从而采取适应的降损措施,达到降低统计线损率的目的。
本文根据配电网的特点,分析和实现了基于支路电流的前推回代法,计算配电网的理论线损;统计线损计算对于单条线路、T接线和变压器建立了计算模型,细化统计线损的计算,为双比值分析建立条件。针对线损管理中数据量大,而线损指标的影响因素又比较多的问题,研究了基于多项要素比较的双比值分析方法,提高了线损分析的全面性和降损措施的针对性。
Line loss ratio is the primary comprehensive technology economic indicator of power supply enterprise which presents the comprehensive level of enterprises in aspects of grid layout and design, production technology, management and so on. Based on the calculation of theory and statistic line loss, this article uses multinomial factors based double ratios to analysis, and takes some proper measures to low down the line loss, then get the purpose of line loss ratio reduction.
According to the features of distribution grid, it analyses and realizes the forward-back substitution based on branch current, calculating the distribution grid’s theory line loss, and builds the calculation model about single line, T connection and transformer, which fractionalized the calculation of statistic line loss and prepared for the double ratio analysis. Aiming at the problem of line loss management that the data quantity is too big and there are lots of effect factors of line loss indicators, this article studies the double ratio analysis methods based on the comparison of multinomial factors, and it improves the comprehensive line loss analysis and direction of line loss reduction methods.
