Core Insights - The Jiangsu Yangzhou to Zhenjiang ±200 kV DC transmission project has been completed and put into operation, marking a significant advancement in China's high-end power equipment sector [1][2] - This project utilizes the innovative multi-source commutation DC transmission technology, which integrates DC transmission, reactive power compensation, and filtering functions, addressing traditional DC transmission limitations [1] - The project enhances the cross-river transmission capacity by three times without the need for new infrastructure, demonstrating the effectiveness of technological upgrades [1] Technical Highlights - The project features three main technological innovations: 1. The hybrid AC-DC connection allows for faster and longer-distance electricity transmission 2. Power mutual assistance enables the two power grids to support each other 3. Reactive power regulation stabilizes voltage and reduces energy waste [1] - The SLCC technology acts as an "automatic voltage stabilizer," making it particularly suitable for integrating variable renewable energy sources like wind and solar [2] Environmental Impact - The project is expected to deliver over 6 billion kWh of electricity annually, equivalent to the annual consumption of approximately 2 million households, with over 30% of this being renewable energy [2] - It is projected to reduce carbon dioxide emissions by about 1.6 million tons each year [2] Future Developments - During the 14th Five-Year Plan period, Jiangsu's installed capacity for renewable energy is expected to exceed 172 million kW - The company plans to construct the Yangzhou-Zhenjiang DC transmission phase three project, further enhancing the "north-to-south" transmission capacity by an additional 10 million kW, contributing to a mixed AC-DC grid structure in the province [2]
