摘要
通过对再热凝汽式汽轮机热力过程的原理分析，结合现场试验的验证，改进了传统的电力系统稳定计算的汽轮机模型，创新性地提出了高压缸功率自然过调系数的概念。改进后的模型，相对于目前动力控制领域一直在用的汽轮机功率模型，在0．1-1Hz的工作频段，其功率响应幅值提高60％左右，和实际对象非常接近。
By means of analyzing the thermodynamic process within reheating turbine and combining with the on-site test results, traditional steam turbine model for power grid stability calculation is improved, and a brand new concept of natural power overshooting coefficient of high-pressure cylinder is proposed. In respect to the power model of steam turbine that is continuously used in the field of power control, the power response amplitude of the improved model is raised by 60% within the working frequency band from 0.1Hz to 1.0Hz, which is very close to actual conditions.
