Example Embodiment

[0027] In order to better understand the present invention, the following further describes the present invention with reference to the accompanying drawings and specific embodiments:

[0028] Due to the high-dimensional non-linear characteristics of the power system, the operating frequency of the system cannot be calculated by analytical algorithms. The full digital real-time simulation system (ADPSS) platform of the power system can be used to study its frequency characteristics. Based on the typical operation mode of the power grid, the simulation calibration is carried out through various typical fault sets. Based on the experience, a coordinated optimization method for high-frequency cut-off measures of isolated grids containing nuclear power units and frequency-related protection of the units is proposed.

[0029] A solution method for optimal operation of power grids containing nuclear power units at high frequencies includes the following steps:

Description

technical field [0001] The invention relates to the technical field of atomic energy unit operation, in particular to a method for solving the optimal operation of a power grid containing atomic energy units at high frequencies. Background technique [0002] Nuclear power generation provides a realistic choice for my country in terms of clean, low-carbon and energy structure adjustment. According to the data of the International Energy Agency, the global nuclear power generation will increase by about 46% by 2040. As of November 2018, there were 42 nuclear energy units in operation in my country, with an installed capacity of 41.77 million kilowatts. There are 14 units under construction, with an installed capacity of 16.31 million kilowatts, and more than 150 atomic energy units under planning. [0003] As the proportion of atomic energy units in the power grid continues to increase, once the power grid where the unit is located suffers a serious fault and causes it to be ...
