2. Background of Standard Development
(1) The outstanding environmentally friendly characteristics of wind power generation make it an important guarantee for China to achieve energy transformation, dual carbon goals, and new power system objectives, holding a significant position in China’s energy system.
(2) The installed capacity and power generation of wind power in China have been increasing year by year, and the grid-connected performance issues such as low and high voltage ride-through and grid adaptability seriously affect the safe operation of the power grid, necessitating verification of wind power grid-connected performance.
(3) Verification of wind turbine grid-connected performance includes both field tests and type tests. Field tests are challenging, have limited operating conditions, and yield less data, with high costs and time requirements; type tests may have inconsistencies between the controller software version and the field operation.
(4) Hardware-in-the-loop testing excels in simulating grid connection conditions and controller software versions compared to field and type tests, making it suitable for verifying and modeling the grid-connected performance of wind turbine inverters. However, there are currently no relevant standards for hardware-in-the-loop testing of wind turbine inverters, making the development of this group standard both necessary and urgent.
