Performance Test of a 660MW Thermal Power Unit Steam Turbine Based on the Background of “Double Carbon”

Abstract

Under the background of "carbon peaking and carbon neutralization", China proposes a new power system with new energy as the main body. Due to the strong randomness, volatility and anti peak shaving characteristics of new energy power generation, in order to promote the consumption of new energy and ensure the power supply, coal power generation units will assume the dual tasks of deep peak shaving and power supply guarantee in the future, gradually changing from electric power supply to regulated power supply. In order to accurately grasp the thermal performance of the steam turbine after the flow passage transformation of the unit, the thermal performance assessment test of the steam turbine of the unit was carried out. Through thermal test, determine the heat rate and efficiency of high, medium and low pressure cylinders of the unit, and provide reference for future economic operation of the unit.
