摘要
电力网的受电端实施无功补偿可减小输电系统的功率损耗;提高无功功率补偿率也可使无功功率经济当量降低。但都由于输电系统的复杂性,而不能确定增设无功补偿装置的最佳容量和经济效益。因此,必须经过经济技术优化计算来确定补偿方案。
Using reactive compensation at the electro-receiving end, the power loss in power transmission systems can be decreased, raising the compensation rate of reactive compensation and the economic equivalent of the reactive power can also be decreased. But owing to the complexity of power transmission systems, it is hard to determine the optimum capacity and economic benefit on adding devices for reactive compensation. Therefore, to determine the compensation plan we have to make economical-technical optimum calculations.
