Core Viewpoint - The successful deployment of China's first domestically developed pumped storage power station air compressor "VM160" marks a significant breakthrough in breaking foreign technological monopolies in this field, promoting the advancement of domestic key energy technology equipment towards high-end, green, and intelligent upgrades [1][3]. Group 1: Development and Significance - The "VM160" air compressor was installed at the Guangdong Meizhou pumped storage power station and has achieved international leading standards after passing scientific achievement appraisal [1][3]. - Pumped storage power stations play a crucial role in stabilizing the integration of renewable energy sources like wind and solar power into the grid, especially as their penetration in the new power system continues to rise [3][4]. - Historically, the air compressor market for pumped storage stations in China has been dominated by foreign brands, leading to high procurement and operational costs, long spare parts procurement cycles, and a lack of technological autonomy [3][4]. Group 2: Research and Development Process - The research and development of the domestic air compressor began in June 2021, involving collaboration among several companies, with a focus on addressing the "bottleneck" issues posed by foreign technologies [3][4]. - The development process included selecting a technical route, structural performance design, equipment manufacturing, and product engineering applications, emphasizing the need for high performance and optimization for large-scale development [4][5]. - The team adopted a "medium-pressure oil-free" technology route, eliminating the need for lubricating oil in the air compression process, thus reducing environmental pollution [4][5]. Group 3: Performance and Economic Impact - The newly developed air compressor achieves a gas pressure of 8.5 MPa and a compression speed of 11.5 cubic meters per minute, with structural strength equivalent to the pressure of 425 cars stacked on a square meter [5][6]. - Compared to imported models, the domestic air compressor shows superior key performance indicators, with noise levels, cylinder body vibration, and motor vibration reduced by approximately 14%, 32%, and 72% respectively [7]. - The estimated economic benefit from replacing imported compressors with the domestic model over a 30-year usage period could reach up to 81 million yuan [7]. - By 2030, China's pumped storage capacity is expected to exceed 120 million kilowatts, nearly doubling the current scale, indicating a significant acceleration in industry development [7].
