Problems solved by technology

However, the existing simulation tools at home and abroad have certain limitations, and cannot well meet the requirements of simulation analysis of AC and DC complex large power grids.
For example, RTDS (Real Time Digital Simulator) is a commercialized electromagnetic transient real-time simulation tool widely used in the world. Although it can realize power system simulation more accurately, it cannot realize large-scale power system due to the limited simulation scale. Simulation; power system analysis software BPA, as a commonly used electromechanical transient simulation program, has the characteristics of large calculation scale, fast calculation speed, good numerical stability, and strong functions. However, because BPA is only a simulation analysis software, it cannot be accessed The external device performs simulation in the actual network device, so the simulation output cannot truly reflect the situation of the actual network device, and does not have the function of real-time simulation

Abstract

The embodiments of the invention provide a power heterogeneous hybrid real-time simulation system and method, relate to the technical field of power systems, and aim to realize large-scale real-time simulation for the power systems. The power heterogeneous hybrid real-time simulation system comprises: a VSC simulation sub-platform, an HVDC simulation sub-platform and an AC system simulation sub-platform, wherein the VSC simulation sub-platform is used for simulating a flexible DC power transmission system; the HVDC simulation sub-platform simulates a high-voltage DC power transmission system by using a second RTDS simulator; the AC system simulation sub-platform is adopted to simulate an AC power transmission system and interacts with the second RTDS simulator in terms of a hybrid real-time simulation interface by using a first FPGA unit. The power heterogeneous hybrid real-time simulation system and method are applied to a large-scale power grid.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to a real-time simulation system and method for heterogeneous electric power hybridization. Background technique [0002] In recent years, with the rapid development of the national economy, my country's AC and DC power systems have also entered a period of rapid development. With the wide application of high-power power electronics technologies such as high-voltage DC, MMC-HVDC, and STATCOM, the scale of AC and DC power grids has become larger and larger. The characteristics of power electronics in the system are becoming more and more obvious, and the operating characteristics of the system are becoming more complex, which puts forward more stringent requirements for the simulation of AC and DC power systems. [0003] In order to deeply study and analyze the complex large power grid with obvious characteristics of power electronics and multi-circuit AC-DC hybrid oper...
