With the sustainable demand for energy development, China's renewable energy power generation industry is developing rapidly. A large number of large-scale renewable energy generating stations represented by wind and solar have emerged. As a large power generation system, the performance of a renewable energy station will directly affect the quality and efficiency of power generation, as well as the impact on the entire grid when it is later connected to the grid. The performance evaluation of a renewable energy station is an important link of its construction and acceptance.
Ti BALUN is committed to the testing activities related to renewable energy power station acceptance and grid-connected performance, and has the corresponding technical capabilities and experience.
