Modernization of the Electric Drive and Automation System of the Sewage Pumping Station

This article proposes a method for the development of an electric drive for a sewage pumping station and an automation system based on the criterion of maximum the effectiveness work. A step-by-step selection is carried out electric drive power units such as power grids, waste crushers, valves, pumps and electric motors. The selection of elements of the process automation system is made, such as a programmable logic controller, a power supply, a circuit breaker, a contactor, soft starters and others. A method of block writing a program for automating a technological process in two programming languages is presented, and the process of creating a general mnemonic diagram of a modernized object with visualization of a technological process on it is described.
