Title:
LOAD CONTROLLING METHOD OF AUXILIARY COOLING SYSTEM FOR GENERATING PLANT AND EQUIPMENT THEREOF
Document Type and Number:
Japanese Patent JPS61138807
Kind Code:
A
Abstract:
PURPOSE:To make plant operation continuable even if auxiliary cooling capacity drops, by comparing the auxiliary cooling capacity with actual plant load, while judging of the propriety of plant operation continuation, and regulating the plant load to be within the range of the auxiliary cooling capacity. CONSTITUTION:The number of operating units of a cooling water pump, a cooling seawater pump and heat exchanger is inputted into a runback judger 26 from a trouble monitor 21 in an auxiliary cooling water system, a trouble monitor 22 in an auxiliary cooling seawater system and a differential pressure detector 23 of the heat exchanger. This runback judger 26 judges a degree of auxiliary cooling capacity and compares it with the actual plant load inputted from a plant load detector 25, whereby the propriety of existing operation continuation is judged, it outputs the judged result to a plant load controller 27. Thus, even if trouble occurs in the auxiliary cooling system and the auxiliary cooling capacity drops to some extent, plant operation is continuable within the range of the auxiliary cooling capacity.
