新农村建设中农村电网建设的探讨

Disscussion in the Rural Power Network Construction in the New Rural Construction

为了解决新农村建设中农村用电水平的不断提高,特别是随着农村经济水平的不断发展,当前实际运行中农村配电网已出现的诸如网络损耗较大而导致供电成本过高、供电可靠性较低、供电电压和频率不满足要求等问题,作者通过对一个典型的农村电网的潮流进行分析,从网络的整体规划布局到局部的输配电设备(如:线路、变压器及无功补偿装置等)方面提出了关于降低网络损耗、提高电压质量和可靠性的具体措施。通过对改建前后的线损率和电压合格率进行计算,表明笔者所提出的方法对现有农村电网改造是有效的。最后,提出了农村电网的发展趋势。

To adapt to the continuous improvement of rural power consumption level in the new rural construction, in particular, with ＇the continuous development of the rural economy, the actual operation of the rural power network has emerged as the high loss of electrical power which leads to a greater cost of the electricity, lower power supply reliability, the supply voltage and frequency do not satisfiy with requirements, etc. Through analysis of a typical rural power network, from the overall planning of the transmission to distribution equipments （such as lines, transformers and reactiveload compensation devices） , the author proposes some specific measures such as reducing power loss and improving the voltage quality and reliability methods. Through calculation for lines power loss rate and percent of voltage pass, the results show that the methods proposed by the author are effective. The directions to the development trend of the rural power network is given.
