Experimental Study on Hydropower Units Based on Virtual and Real Integrated Simulation Platform

摘要:

随着以化石燃料为基础的传统能源技术，逐渐被如风能、光伏发电、绿色氢电解和潮汐能等清洁能源技术所取代，且电力系统互联规模不断增大，调度运行方式与控制日趋复杂。在此背景下，开展担任调峰调频任务的水电机组的试验研究对提高电力系统稳定性、抗扰动能力等具有重要意义；然而，由于成本和风险巨大，试验类型受到极大限制。为此，构建包括真实部件和虚拟部件的虚实结合型水轮机调节系统仿真平台，并通过自动开机、空载扰动、连续增负荷、甩负荷和故障模拟等试验验证了基于虚实结合型仿真平台的水电机组试验研究的合理性。研究结果表明，构建的虚实结合型仿真平台可有效模拟水电机组过渡过程，以低成本、低风险实现了水电机组调节系统的常规试验与故障模拟试验。

Abstract:

With traditional energy technologies based on fossil fuels gradually being replaced by clean energy technologies such as wind energy, photovoltaic power generation, green hydrogen electrolysis and tidal energy, and the scale of power system interconnection continues to increase, the scheduling and operation methods and controls are becoming increasingly complex. In this context, conducting the experimental research on hydropower units which undertake the peak shaving and frequency regulation tasks is of great significance for improving the stability and disturbance resistance of power system. However, due to the huge cost and risk, the types of experiments are greatly limited. To this end, a virtual and real integrated simulation platform for hydro-turbine regulation system is constructed, which includes both real and virtual components. The rationality of experimental research on hydro-turbine units based on the virtual and real integrated simulation platform is verified through experiments such as automatic start-up, no-load disturbance, continuous load increase, load rejection and fault simulation. The research results show that the constructed virtual and real integrated simulation platform can effectively simulate the transition process of hydropower units, and achieve routine testing and fault simulation testing of regulation system of hydropower units at low cost and risk.
