APPLICATION OF FUZZY CONTROL TECHNIQUE TO THE CENTRAL AIR-CONDITION REFRIGRATION SUPERIOR SYSTEM IN A HIGH-VOLTAGE SWITCH ROOM OF POWER PLANT

The central air\|condition refrigeration superior system used in a high\|voltage switch room of power plant is an important part that compose complex automatic control system of operating process in power plant, which is significant to the safe operation. The central air condition system for switch room, being of characteristics of non\|linearity, time\|variation, and distributed parameters, is a complex system. In order to guarantee the system to operate safely and steadily, an effective control algorithm may be adopted. Fuzzy control algorithm highly imitates intellectual ability of human. It can achieve ideal results in case of lacking accurate model of system. On the foundation of deeply analyzing object's characteristics of central air\|condition supervisor system, a kind of fuzzy control algorithm which gears to actual circumstances and successfully realizes on\|line control of several refrigerating units is applied. Satisfactory results are obtained, in the actual operating process of the power plant, the aim of energy sparing is reached.
