Description
technical field [0001] The invention relates to the technical field of power system simulation, and more specifically relates to the establishment of a PSCAD-based nuclear power unit power and electrical hybrid simulation platform. Background technique [0002] China is vigorously developing nuclear power. After nuclear power is connected to the power system, it will have a major impact on the system. With the continuous increase of the peak-to-valley difference in the power grid and the large-scale development of nuclear power, the necessity of nuclear power to participate in peak regulation is becoming more and more prominent. The development trend of nuclear power and the requirements of system grid connection require in-depth research on the participation of nuclear power in peak regulation and the change of system daily load characteristics, the load tracking mode of nuclear power units and the requirements of peak regulation range. For this, it is necessary to establish...
