Abstract

The Sea Water Lift Pump (SLP) system is responsible for maintaining the open canal level to provide the suction flow of Circulating Water Pump (CWP) at the set point. The response of the SLP system is so slow that it is difficult to maintain an optimal open canal level by manual or two step pump speed control operation and to reduce overflow of seawater. The objective of this paper is to apply the fuzzy control method, which can utilize the flexibility and the heuristic operation strategy employed by operators, to SLP system in fossil fired power plant. In order to verify a proposed fuzzy system, we developed simplified models such as mathematical model of SLP, CWP, seawater level and intake canal. The result of the simulation test shows that the proposed fuzzy control method can reflect successfully the experience gained in skilled manual operation. It is expected that the fuzzy control can contribute to the reduction of power consumption of SLP, human error and man power, and to the improvment of the reliability and safety of the plant operation.

火电厂模糊海水提升泵系统设计

海水提升泵(SLP)系统负责维持开渠水位，以在设定点提供循环水泵(CWP)的吸力流量。由于SLP系统的响应速度较慢，很难通过手动或双级泵调速操作来维持最佳的明渠水位，也难以减少海水溢流。本文的目的是将模糊控制方法应用于火电厂SLP系统，该方法可以利用操作者的灵活性和启发式操作策略。为了验证所提出的模糊系统，我们建立了简化模型，如SLP、CWP、海水水位和进水渠数学模型。仿真试验结果表明，所提出的模糊控制方法能较好地反映熟练人工操作的经验。期望模糊控制能够降低SLP的功耗、人为误差和人力，提高电厂运行的可靠性和安全性。
