Control System Design And Application Of 300MW Power Plant

With the rapid development of large capacity of thermal power generating unit as well as the complex system, the risk of danger will be increased once an accident happened. Therefore, it puts forward higher requirements to its control system. It needs continuously increasing safety and decreasing the unpredictable accident rate. It is important to apply scientifically and standardized management.This paper is based on 2*300MW condensing steam power plant invested by JSWSL company. It carries out the design of control system aiming at the feature and control requirements of 300MW power plant. The paper mainly states the design and application of MaxDNA system applied in Project JinDal in India. On the basis of national standard and safety code standard of India, this paper researches on the hardware configuration, Software Programming, Human-Machine interface and control strategy. It also compares and analyses the practical problem appearing in debugging process.Finally, the writer has a performance tests in MaxDNA system to insure correct connection and normal operation of I/O channel. The condition of system is well and the test run proceeds 30 days smoothly. It completely achieves the demand of processing equipment and it ensures the stable operation of subsystem and important auxiliary. The successful application of MaxDNA provides a reference and guidance to congenic system applying and designing in Thermal power field. At last, the writer hopes the successful experience of control system apply in 600MW and larger thermal power generating unit.
