Power generation system used method of estimating the maximum power generation capacity of the combined cycle gas turbine power plant or a single cycle, with the same method, and how to control the power reserve that has been specified

摘要

I disclose the estimation unit for estimating in real time the maximum power generation capacity of the combined cycle gas turbine power plant or a single cycle. In accordance with the present invention, the maximum power output capacity and power is calculated based on mathematical process models actual practical. Is compared with the measured output power and the output power actual Subsequently, the calculated model estimation error is obtained. Correction signal is derived based on the model estimation error. Maximum power generation capacity of the correction signal is used in later steps, the calculations are corrected. Furthermore, the controller for operating the combined cycle gas turbine power plant or single cycle power reserve specified to be maintained also disclosed. The controller operates in a control hierarchy level of the load instruction. Was used as a reference to estimate the maximum power generation capacity, and reduces the load offset that is required, is used as the upper limit of the load target value resulting signal the controller. Load offset that is required to follow from the reserve power that has been specified. And temporary requirements and static requirements are included in the designation of reserve power.
