摘要
我国中压配电网的线损计算面临着算法繁琐、准确性不足的问题,原因在于目前的线损算法的需求数据和采集数据匹配程度较低。针对此现象,提出了基于负荷曲线的线损计算方法,首先根据实际用电数据建立负荷曲线模型,计算出日负荷标幺值、日负荷有功功率、日负荷无功功率,再使用前推回代法精确计算日线损值和线损率,最后根据江苏省某市某供电企业的实际配电线路进行算例分析,验证了该计算方法的有效性。
The line loss calculation of China's medium-voltage distribution network faces the problem of cumbersome algorithm and insufficient accuracy,because the current line loss algorithm has a low degree of matching between the demand data and the collected data.In view of this phenomenon,a line loss calculation method based on load curve is proposed.Firstly,the load curve model is established according t o the actual electricity consumption data,and the daily load standard value,daily load active power and daily load reactive power are calculated.Then,the daily loss value and line loss rate were accurately calculated using the push-forward resurge.Finally,according to the actual distribution line of a power supply enterprise in a city in Jiangsu Province,the effectiveness of the calculation method is verified by an example analysis.
