Feed water system's optimization in thermal power plants (case study) by vector control inverters

By the day by day diffusion of electrical energy Consumption and product expenditure's increase, saving's need consumption, is felt rather than past. Pump's systems averagely consume productive electricity near to 30% in industrial countries so that older pumps are usually moved via inductive motors and A - Synchron motors. (Mostly induction squirrel motors ) and reluctant switch motors are recently used, too. Electrical energy consumption of pumps is 31% in America. Different studies have been showed that by optimizing pipelines, pumps and their control's systems their energy consumption can be saved between 30 % to 50%.old control systems cannot be effective in improving energy consumption .using variable velocities drives by the help of electrical power is used for improving energy consumption .also electrical power Inverter's source is investigated in pump's drive reluctancy.in most plans, during a pump self-life's time, half of the expenditures are related to the electricity consumption . Although the early expenses of purchase and pump installation includes 10% of the whole expenditure, logic use of energy, conservation of energy resources, the amount's reformation of energy consumption in consuming parts of energy, reduction of greenhouses gas and air pollution's reduction, reformation of existent case and competitive excellence in economical establishments, can be expressed as the purposes of optimization of energy consumption. Power plants as forerunners of products can play an important role by optimizing new systems or by reforming them. Against this intention, for increasing the efficiency of a 1300 megawatt unit and according to not using drive system in this unit's pumps, the beneficial use of this system is mentioned, and economically by considering load's profile has been investigated.
