EFFICIENCY ANALYSIS OF MOTOR 2A CONDENSATE PUMP AT STG 2.0 TAMBAK LOROK STEAM POWER PLANT PT INDONESIA POWER SEMARANG

Electrical Engineering

Gas and Steam Power Plant (PLTGU) is a power plant that utilizes gas and steam power as a turbine propulsion that will drive a generator to produce electricity. In the operation of generating electrical energy at the PLTGU, it is necessary to transfer a material in the form of liquid or gas. In the transfer using a pressure regulator such as a pump. A condensate pump or condensate pump is one of the pressure regulating equipment whose existence is very important in the water-steam cycle of gas and steam power plants. Because of the important role of pressure regulating equipment for a substance, it is necessary to analyze the power efficiency of the Condesate pump motor so that the water supply to the deaerator can be transferred optimally. The condensate pump functions to transfer condensate water from the condenser to the deaerator and feed water tank. Based on the results of the analysis, the efficiency of the Condesate pump motor is in the range of 85% to 95%. Because, in general, the efficiency of a motor never reaches 100% when working with an existing load due to various factors that cause power losses that are difficult to avoid in induction motors.
