Abstract: With the continuous growth of the national economic level, various industries have obtained very broad development prospects. At the same time, the demand for energy is also increasing, especially electric energy, which has now become the second largest social development. At the same time, it also puts forward more stringent requirements for power enterprises and power generation technology. Based on this, this paper discusses and analyzes the potential problems in the operation of the auxiliary steam turbine in the power plant, and puts forward some effective optimization countermeasures, hoping to further improve the operation efficiency of the auxiliary steam turbine and ensure the safe and stable operation of the power plant.
