农村电网的无功补偿.doc

论文题目:农村电网的无功补偿专业:电气工程及其自动化本科生: 指导老师: 摘要无功电源的合理规划和运行也是电力系统安全经济运行的保障。衡量电能质量的一个重要标志是系统的电压水平, 而系统的无功平衡是保证电压水平的基本条件。电压是电能质量的重要指标之一, 电压质量对电网稳定及电力设备安全运行、线路损失、工农业安全生产、产品质量、用电单耗和人民生活用电都有直接影响。无功电力是影响电压质量的一个重要因素, 电压质量与无功是密不可分的。以一个配电线路为例, 比较了几种补偿容量的方法,补偿容量最佳分配的计算方法。本论文最后介绍了电压无功控制系统中的三级电压控制系统以及变电站 VQC 控制装置的原理。关键词: 电压无功电源无功补偿无功控制 Subject : In rural areas the reactive pensation Specialty : Electric Engineering and Automation ABSTRACT Reactive Power reasonable planning and operation of the power system is safe and economic operation of protection 。 electric power is an important indicator of system voltage level. The balance is reactive voltage level to ensure the basic conditions 。 Voltage power quality is one of the important indexes , Voltage quality of power system stability and the safe operation of electrical equipment, wiring losses, industrial and agricultural production safety, product quality, electricity intensity and the life of the people will have a direct impact on electricity consumption. Reactive power is affecting the voltage quality was a major factor in the quality of voltage and reactive power are inseparable. To a distribution line as an example, Comparison of several methods pensation capacity of pensation capacity of the distribution of the best methods of calculation. At the end of t his paper , introduced a voltage and reactive power control system of three voltage substation control system and VQC substation control device Principle .
