【摘要】 新能源装机已成为云南电网内第二大装机电源,网内调频惯性下降,调频能力不足;南方电网已规定并网新能源场站应具备调频能力,新能源场站的调频能力改造及检测工作已在同时逐步开展,检测工作是验证场站调频能力的重要手段。本文提了一种采用标准数据源、仿真波形回放、实测波形回放结合,从调频功能、防扰动性能等方面开展新能源场站单机、站级调频能力测试的方法,并首次在南方电网内的风电场、光伏电站得以验证。更多还原

【Abstract】 The installed new energy has become the second largest installed power source in Yunnan power grid, resulting in low system inertia and insufficient frequency regulation capacity. China southern power grid has stipulated that the grid-connected new energy station should have the capability of frequency regulation. The modification and detection of frequency regulation capacity of the new energy station have been carried out step by step at the same time. The detection is an important means to verify the frequency regulation capacity of the station. In this paper, a method was proposed to test the frequency regulation capability of new energy field stations at the individual and station level by using standard data sources, simulation data playback and measured data playback, and from the aspects of frequency regulation function and anti-disturbance performance, etc., which was verified in the wind farm and photovoltaic power station in the southern power grid for the first time.更多还原
