Abstract

Abstract Systems for remote monitoring and control on energy consumption, efficiency and proper operation of the controlled objects are very often used in different spheres of industry, building automation, electricity distribution network etc. Various types of intelligent energy meters, PLCs and other control devices are involved in such systems. On the other hand, soft starters are widely used in industry and building automation for control on asynchronous drives when the speed regulation is not a mandatory requirement. They are cheaper than inverters and frequency converters and allow temporal reduction of the torque and current surge during start-up, as well as smooth deceleration. This is why the study of the principles of operation and setting up of intelligent energy meters, soft starters and PLC is very important. A laboratory system has been designed and built. An asynchronous motor is controlled by a soft starter and remote monitoring and control by contemporary devices has been provided. A methodology of design and setting up has been developed.
