Core Insights - The first nationwide 9F heavy-duty gas turbine flexible excitation system based on insulated gate bipolar transistor devices has passed factory testing, marking a significant breakthrough in flexible excitation technology from medium and small units to large units [1] Group 1: Technology and Innovation - The excitation system acts as a "voltage stabilizer" for generators, maintaining grid voltage stability during sudden increases or decreases in electricity load [1] - The system utilizes fully controlled insulated gate bipolar transistors, upgrading traditional current source excitation control characteristics to voltage source, enhancing generator voltage support capability by over 200% and dynamic reactive response capability by over 60% [1] - The cost of the new system is only 20% of traditional methods for adding reactive power compensation, achieving significant improvements in grid stability with a "small investment" [1] Group 2: Market Context - The push for "dual carbon" goals has led to a continuous increase in installed capacity of renewable energy sources such as wind and solar power, alongside the expansion of cross-regional DC transmission and the integration of power electronic devices like charging piles and smart grid equipment into daily life [1] - The intermittent and volatile nature of renewable energy generation has increased the frequency and magnitude of grid voltage fluctuations, highlighting the inadequacies of traditional excitation systems that use thyristors, which have slow response times and insufficient voltage support capabilities [1]
