System and method for monitoring and optimizing flow characteristics of high control valve of steam turbine in real time

The invention provides a system and a method for monitoring and optimizing flow characteristics of a high control valve of a steam turbine in real time, and belongs to the field of steam turbine valve testing. The system comprises an acquisition module used for acquiring data of a steam turbine high control valve in real time; the conversion module is used for converting the data of the steam turbine high control valve from analog quantity to digital quantity; the processing module is used for judging whether the flow characteristic of the high control valve is changed or not according to the digital data of the high control valve of the steam turbine; calculating a flow characteristic calculation value according to the data of the high control valve of the steam turbine, and optimizing the flow characteristic calculation value according to a preset linear reference curve; and the control module is used for testing the high control valve and outputting measured data of the high control valve. The method can b
