New energy multi-wind field real-time online modeling system and method

Abstract

The invention provides a new energy multi-wind-field real-time online modeling system and method. The system comprises an upper computer, a real-time digital simulator (RTDS), a GBH module and a switch module, and the real-time digital simulator comprises a plurality of RACKs. The RACK and the GBH module are in optical fiber communication connection through a simulation synchronous optical fiber and a data transmission fiber. And the switch module is used for sending and receiving the compiled files between the upper computer and the RCAKs. According to the method, RACK information is reasonably configured, calculation synchronization and data sharing among multiple RACKs are finally achieved, and RTDS modeling work of the wind field level is jointly completed. And real-time simulation modeling of multiple wind fields is realized by reasonably distributing computing resources of the RTDS.

Description

technical field [0001] The invention relates to the field of new energy technology, in particular to a real-time online modeling system and method for multiple wind fields of new energy. Background technique [0002] Energy is an important material basis for economic and social development. With the worldwide energy shortage, the development and application of renewable energy industries, such as wind power, photovoltaic power generation and other technologies, has become the fastest-growing hot spot among all kinds of energy. [0003] At present, most of the simulation verifications on wind power generation use non-real-time off-line computer simulation software, which is easy to operate and does not require high computing performance of the computer. However, due to the lack of computing power of the off-line computer simulation software, the off-line simulation cannot verify the simulation system in real time, and the actual simulation time is often tens or even hundreds ...

AI Technical Summary

Problems solved by technology

At present, most of the research and modeling of wind power generation for RTDS digital real-time simulators are based on single-machine simulation modeling, so RTDS can give full play to its excellent computing power and achieve the effect of "real-time simulation", but there are few studies at present Real-time digital simulation modeling of multi-wind turbines and multi-wind farms using RTDS

The main difficulty is that a single RTDS can complete stand-alone modeling excellently, but when the modeling object rises to the wind farm, each wind farm contains hundreds of wind turbines, so it is necessary to solve the joint simulation and resources between multiple RACKs The question of fair distribution
