AGC and artificial dispatching based real-time control framework of power system thermal stability

The rapid growth of power loads and the lag in power grid construction make the thermal stability problem of the load centre more and more prominent. In order to improve the effectiveness and automatic level of thermal stability control of power system, a real-time control framework based on and AGC system and telecontrol was proposed. Firstly, the design principle and basic functions of real-time control of thermal stability were clarified; and then, on basis of short review and comparative analysis of three control means, a real-time control framework, that AGC serving as preventive control means and corrective control means when the overload is slight, telecontrol by dispatchers serving as corrective control means when the overload is severe, was proposed; Lastly, the key technologies of telecontrol-based control and AGC-based real-time control methods were analysed in detail.
