Discussion on necessity and feasibility of Hainan nuclear power plant

Based on the analysis of Hainan electric market and energy resources situation, the necessity of Hainan nuclear power plant was discussed in the paper.And the feasibility of the nuclear power plant was analyzed through two aspects:safety and stable operation of power grid and peak regulation.Through power system stability calculation, it is indicated that when Hainan power grid is connected with China Southern Grid through 500 kV AC line and its load reaches to 4 000 MW, Hainan power grid can bear the impact due to the sudden lost of the large-capacity nuclear generator.Through power system balance calculation, it is indicated that when Hainan load reaches 5 000 MW, the power system can satisfy the peak regulation requirement for 2×650 MW nuclear generators;but it's needed to send out some redundant power during extreme bottom load period.
