【摘要】：随着我国经济的快速发展,用电负荷不断增加,电网不断延伸、扩展。经济的快速高质量增长使电能质量问题也得到了人们的关注,其中中压配电网的电压越限问题普遍得到用户的关注。政府根据相关标准开始对供电企业进行考核,供电企业也对电压越限的治理投入了大量的资金。随着西双版纳地区经济的快速发展,当地供电负荷近年来一直保持两位数的快速增长,因此,当地用户对电能质量的要求逐年提升。且西双版纳地区中低压配电网存在典型的线路供电区域较大、负荷较轻、线损较高的状况,随着用电负荷的大量增加,电压质量的问题日益突出。本文以西双版纳地区配电网10kV馈电线路典型电压越限现象为研究对象,进行原理分析,将其影响原因分为三类:上级电网运行与控制方式、网架结构、负荷特性;并利用计量监测数据对配电网潮流计算中变压器模型进行优化,使计算结果与实际运行数据相吻合;最终确定了以变电站内部电压调整优化与馈电线路电压分散控制相结合的对配电10kV馈电线路典型电压越限现象的综合治理策略通过对西双版纳地区中压配电网典型电压越限综合治理的研究,让我们对有普遍意义的10kV馈电线路典型电压越限现象的成因与治理方法有了准确认识。我们需要不断钻研,继续强化电网建设,不断优化电网资源,才能在不断发展的条件下实现安全、稳定、经济、可靠供电的目标。
[Abstract]:With the rapid development of China's economy, the electricity load increased, the grid extension expansion. Rapid economic growth with high quality makes the power quality problem has been people's concern, the voltage of medium voltage distribution network limit problems generally get the user's attention. The government according to the relevant standards to assessment of power supply enterprises spend a lot of money management of power supply enterprise is limited to voltage. With the rapid economic development in Xishuangbanna, the local power supply in recent years has maintained rapid growth, so the local two digit, the demand on power quality is increasing year by year. And the low voltage distribution network in Xishuangbanna area has a typical power line area is large, the load is light, the loss of high status, with the substantial increase in electricity load, power quality problems have become increasingly prominent. This article takes the Xishuangbanna area feed distribution network 10kV The typical power line voltage limit phenomenon as the research object, analyze the principle, the influence factors are divided into three categories: the load characteristics of power grid operation and the control mode, grid structure; and use of power flow calculation in transformer model to optimize the measurement and monitoring data, the calculation results coincide with the actual operating data; finally the research of Xishuangbanna medium voltage distribution network typical voltage limit of comprehensive treatment by integrated management strategy in a substation optimization adjusting voltage and feed line voltage dispersion of distribution feeders 10kV typical voltage control of a combination of limit phenomenon, let us on the 10kV feeder line causes a general sense of the typical voltage limit phenomenon with the treatment method with accurate understanding. We need to continue to study, continue to strengthen power grid construction, constantly optimize the network resources, in order to continuous development Under conditions, the goal of safe, stable, economical and reliable power supply is achieved.
