Optimization of Automatic Adjustment Parameters for Large Capacity and Large Delay Systems
The parameter optimization of large capacity and large delay regulation systems has always been a major challenge for thermal and electrical workers.The public system of the third phase of Heze Power Plant has a large water tank volume(up to 2 000 m3)and a thicker water supply pipeline(Φ325×6 mm),the water level in the tank is difficult to control,resulting in significant fluctuations in the water supply flow rate and directly affecting the water consumption of industrial water tank users.To solve this problem,we have successively replaced the water supply electric valve with a regulating valve,installed an ultrasonic level gauge,entered the DCS system,designed an automatic adjustment control logic configuration,and optimized the automatic adjustment parameters multiple times to maintain a relatively stable liquid level in the industrial water tank for a long time,which can effectively ensure the long-term stable operation of the equipment.
