考虑分布式电源接入的配电网设备利用率评估方法

An Efficiency Evaluation Method of Distribution Network Considering Distributed Generation

公平合理的配电网设备利用率评估,对于提高配电网的质量和企业的经济效益具有重要意义,并且分布式电源的接入对传统的配电网设备利用率评估产生重要影响。提出一种新的配电网设备利用率评估方法:在分析分布式电源对配电网设备利用率的影响中,评估指标选取常用的负载率、容量因子为例,统计口径方面选取下送功率、电量,全社会用电功率、电量以及绝对值计算全面分析分布式电源对设备利用情况的影响。算例分析表明,多统计口径可以更加全面、客观地反映配电网设备的利用率。

Fair and reasonable evaluation of power distribution network equipment utilization rate has a great significance for improving the quality of power distribution network and the economic efficiency of enterprise.Moreover,the access of distributed power supply will have an important influence on the traditional power distribution network equipment utilization rate evaluation.This paper presents a new method for evaluating the power distribution network equipment utilization rate,in the analysis of the influence of the distributed power supply about the power distribution network equipment utilization rate,using the load factor and capacity factor as examples,in the sides of statistical caliber,selecting send power,quantity of electricity,electrical power and electricity consumption of the whole society as well as the computes absolute value to analyze comprehensively the influence of the distributed power supply to the condition of utilization equipment.The analyses of numerical example shows that many statistical calibers could reflect the rate of power distribution network equipment utilization more comprehensively.
