Optimization Dispatching Study Of Water Circulating Pump

Optimization dispatching study of water circulating pump includes low pressure system of steam turbine, condenser system, water circulating pump and pipe system. This thesis has made a concrete analysis of running characteristics of three subsystems on the basis of profound theoretical research. And take Shandong Shengli Power Station as an example, the relational curve is obtained through calculation which between turbine power and back pressure, back pressure and exhaust steam amount, turbine power and inlet water temperature of cooling water. Then on the basis of three groups of curve, the optimum operation mode is obtained with the systematic view, that is to say the optimum operation mode in different circulating water temperatures and loads is approached. And the optimum condition fig is regimented. It supplies compacted basis and evidences for scientific instructing economic dispatch of water circulating pump in running.
