无功补偿并联电容最优节能分布模型建构及验证
|
摘要
检测电能质量的一个常用标准是无功功率,无功功率与负荷的正常运行密切相关。日常的生产生活中,阻感负载是主要负载,比如变压器、异步电动机等,在工作时,大部分无功功率被消耗。要提高阻感负载的工作效率,最有效的方法就是进行无功补偿。无功补偿也能提高整个电网电压的稳定性,减少设备的容量,提升用电效果。日平均无功电流或者功率的线密度分布,能够根据电网母线负荷无功电流或者功率的即时分布获取。由此本文构建无功补偿并联电容最节能分布模型,分析指定补偿位置的最节能的电容分布,给定最节能容量、位置分布和联合分布。对最节能分布模型的可行性进行验证。
A common standard for detecting power quality is reactive power, which is closely related to the normal operation of the load. In daily production and life, the resistive load is the main load, such as transformers, asynchronous motors, etc., most of the reactive power is consumed during operation. To increase the efficiency of the resistive load, the most effective method is to perform reactive power compensation. Reactive power compensation can also improve the stability of the entire grid voltage, reduce the capacity of the equipment, and improve the power consumption. According to the instantaneous distribution of the reactive current or power of the grid bus load, the linear average distribution of the daily average reactive current or power can be obtained. Therefore, this paper constructs the most energy-efficient distribution model of reactive power compensation shunt capacitors, analyzes the most energy-efficient capacitor distribution of the specified compensation position, and gives the most energy-saving capacity, position distribution and joint distribution. Verify the feasibility of the most energy-efficient distribution model.
