摘要
为解决电子线路投切控制器对工作环境和电源质量要求高、可靠性差的问题,提出基于S7-200系列PLC的无功自动补偿控制系统的设计方案。无功自动补偿控制系统能有效提高电网的功率因数,降低供电变压器及输送线路的损耗,改善供电环境,节能效果显著。
In order to solve problems of high demands on the work environment and quality of power sup- ply, and poor reliability of electronic circuit switching controller, proposed the design plan of reactive power automatic compensation based on S7 -200 series PLC. The reactive power automatic compensation control system can effectively improve the power factor, reduce the loss of power transformers and trans- mission lines and improve the power supply environment, so it has remarkable energy -saving effect.
