Embodiment Construction
[0041] Aiming at the shortcomings of the existing Coordinated Control System (CCS) in the large supercritical units mentioned in the background technology that it is difficult to meet the fast load response requirements of the power grid, and it is easy to cause large fluctuations in parameters such as main steam pressure and main steam temperature, the present invention establishes a And condensate water throttling steam turbine unit load forecasting neural network model, and then a dual intelligent optimization control method for unit load based on intelligent model is proposed. The present invention mainly includes two parts.
[0042] 1. Establish a neural network model for load forecasting of steam turbine units that takes into account condensate throttling, including the following specific steps:
[0043] (1) Select model input and output parameters
[0044] The opening of the deaerator water level regulator is used to replace the condensate flow as the model input, and ...
