Abstract

The embodiment of the invention provides a fault early warning method and device for a cooling tower fan, and electronic equipment. The method comprises the following steps: obtaining historical operation data of the cooling tower fan at different measuring points under a healthy working condition; based on the historical operation data, using a gradient lifting algorithm to train a basis regression device to obtain a prediction model; predicting a reference value of a target operation parameter of the cooling tower fan by using the prediction model; and performing fault early warning on the cooling tower fan according to the reference value of the target operation parameter and the actual value of the target operation parameter. The generalization capability and robustness of the gradient lifting algorithm are excellent, so that the prediction precision of the reference values of the important parameters of the cooling tower fan is improved, the reliability of the early warning result of the cooling tower fan is high, and safe and stable operation of the cooling tower fan is ensured.

Description

technical field [0001] The present application relates to the technical field of gas-fired power generation, in particular to a cooling tower fan failure warning method, device and electronic equipment. Background technique [0002] The cooling tower fan is an important auxiliary machine of the combined cycle unit that uses the mechanical ventilation tower to cool the circulating water of the condenser. The working environment of the cooling tower fan is relatively harsh and is prone to various failures. Therefore, early warning of the failure of the cooling tower fan extremely important. [0003] In some scenarios, the cooling tower fan is given an early warning by comparing in real time whether the deviation between the actual value of the important parameters of the cooling tower fan and the reference value exceeds the threshold. The accuracy of the reference value is an important condition to ensure the reliability of the early warning. In the related technology, the re...
