Combined control platform of deep peak shaving steam turbine based on stress and service life

The invention provides a stress and service life-based combined control platform for a deep peak shaving steam turbine. The platform comprises a processing server which is used for obtaining a monitoring instruction, determining first equivalent stress of specific positive and negative characteristics of the high-temperature key component based on the monitoring instruction, determining stress monitoring data and first type of service life monitoring data of the high-temperature key component according to the first equivalent stress, and sending the stress monitoring data and the first type of service life monitoring data to the processing server; determining a second type of service life monitoring data of the high-temperature key component, determining a target change rate of closed-loop control parameters of the steam turbine according to multiple types of monitoring data of the high-temperature key component, and generating a closed-loop control instruction according to the target change rate; and the ste
