The Research On The Peak Regulating Modes Of 300MW Fossil-fired Unit

The research object is the load distribution and working characteristic of big power plant that working with mutative load .In order to analyze and research deeply in working characteristic and energy expend of mathematical model, this paper mainly focused on working parameter and the problem of unit working with variational load request. To analyze the peak regulating capability of fossil-fired set, must synthesize the security, the economics, the flexibility of peak regulating operation. Consulting the peak regulating experiences of the domestic an international other type fossil-fired sets, from both the theories and the running experiences, the author investigated the security and the flexibility if the type set has taken on the peak regulating operation, verified the possibility that the type set to adopt two-shift peak regulating operation, According to 300MW unit in LaiCheng Power Plant,studying the peak regulating operation economics of the type set. Adopting the thought of the neutral line factor, the author deduced calculating formula for start-stop energy loss in two-shift operation, and verified quantitatively the economical feasibility of 300MW unit in two-shift peak regulating operation.
