Fault simulation method for communication link of electronic controller of gas turbine control system

The invention provides a gas turbine control system electronic controller communication link fault simulation method, and relates to the technical field of gas turbine power plant fault diagnosis. The method comprises the following steps: acquiring a sensor process signal from a gas turbine controller system, and performing data preprocessing to form an original data set; inputting the original data set into an IO board card fault simulation module, adding fault form data, and adjusting board card performance calculation parameters, so that the performance index value of the board card deviates from a preset performance index normal range; inputting the performance index value of the board card into a communication link performance calculation module, and calculating the performance index value of a link; and judging whether the performance index value of the link exceeds a preset normal range or not so as to determine whether the communication link has a fault or not. By obtaining the performance index value
