Abstract: A method of automatic load regulation, operation and protection for steam turbine and motor combined drive and power generation in converter saturated steam utilization, which relates to the technical field of low-pressure saturated steam utilization, to solve the problems of steam instability, low energy utilization efficiency, and unstable system operation in existing technique. Technical points: S1. setting engagement speed; S2. speed control mode; S3. switching to a valve control mode after successfully engagement; S4. valve position automatic mode activation; S5. entering automatic mode; S6. reducing the valve position adjustment rate; S7. reading, by the DCS of the drive steam turbine system, the comprehensive thermal storage index value and the preset valve position corresponding to the thermal storage value; adjusting the valve position to the valve position corresponding to the read heat storage value.
