Intelligent Testing System for AC Load Based on PLC

Abstract:

The backup power plays an important emergency supply role in industrial field and agricultural field. The emergency supply power (such as generator and Uninterrupted Power System etc.) is a standby state in most of the time. These devices only start to ensure electricity supply on the condition of power lose or power failure. It is difficult for users to know its real load performance. This paper designed a kind of intelligent AC (Alternating current) load test system based on PLC (Programmable Logic Controller) to solve the problem. There are signal acquisition part, the dummy load component and parameter display control part in testing load testing system, which can meet the general users of emergency power supply in daily inspection. We design the intelligent control for high performance and fine test users. The test results show that the intelligent AC load systems based on PLC can effectively detect power generation units and UPS emergency power supply in according with national standards.
