1.概述 用电设备在一定电压和功率下,功率因数越低,所需电流越大,因而增加了线路损耗并使供电设备不能充分利用,所以采取措施提高功率因数具有重大的经济意义。在低压配电系统中,功率因数补偿控制一般采用的是专用的功率因数补偿控制器(也称无功功率补偿控制器)。而在智能型低压配电系统中,由于专用功率因数补偿控制器不具有数据通信端口,不能通过现场总线远距离传输数据,供监控系统处理。为了解决这个
1. Overview Electrical equipment at a certain voltage and power, the lower the power factor, the greater the current required, thereby increasing the line loss and make the power supply equipment can not make full use of, so take measures to improve the power factor of great economic significance. In the low-voltage power distribution system, the power factor compensation control is generally used is a dedicated power factor compensation controller (also known as reactive power compensation controller). In the intelligent low-voltage power distribution system, because the dedicated power factor compensation controller does not have a data communication port, it can not remotely transmit data through the field bus for the monitoring system to process. In order to solve this
