Abstract

The invention discloses a new energy unit control protection real-time digital simulation model optimization method and device, and the method comprises the steps: converting a control protection real-time digital simulation model of a new energy unit into a C language file, and converting the C language file into a library file; the real-time digital simulator can read the logic of the control protection real-time digital simulation model of the new energy unit, so that the primary model of the new energy unit is controlled through the library file, a preset simulation test is carried out, and the simulation result of the simulation test is compared with the actually measured data, so that the real-time digital simulator can control the control protection real-time digital simulation model of the new energy unit. And adjusting the parameters of the control protection real-time digital simulation model to optimize the control protection real-time digital simulation model, thereby improving the simulation accuracy of the control protection real-time digital simulation model of the new energy unit.

Description

technical field [0001] The invention relates to the technical field of model optimization, in particular to a method and device for optimizing a real-time digital simulation model for control and protection of new energy units. Background technique [0002] The connection of large-scale new energy to the power grid will lead to weak grid structure and insufficient voltage support capacity. If the control and protection actions of new energy units are not correct, it may cause large-scale new energy chains to go off the grid. The physical process of these electromagnetic transient time scale changes will directly affect the interaction between the power grid and new energy, and affect the stable operation of new energy and the power grid. Therefore, it is of great significance to establish an accurate real-time digital simulation model of new energy units for the research on the characteristics of new energy grid connection. [0003] However, most of the existing real-time d...
