Core Viewpoint - The successful commissioning of the 750 kV transmission and transformation project from Shaanxi to Gansu marks the completion of Gansu's 20th and 21st inter-provincial connection lines, enhancing the province's power transmission capacity and supporting clean energy consumption in the northwest region [1][2]. Group 1 - The project starts from the 750 kV Xizhou substation in Shaanxi and ends at the 750 kV Quzi substation in Gansu, with a total length of 144 kilometers and the construction of two 750 kV double-circuit lines [2]. - The newly commissioned equipment includes two 210 MVar high-voltage parallel reactors and four 750 kV circuit breakers, significantly improving the operational reliability and flexibility of the Qinyang converter station [2][4]. - Gansu's power grid has established two ultra-high voltage transmission channels, with plans to accelerate the construction of additional external transmission lines to enhance energy resource advantages [7]. Group 2 - The construction faced complex terrain and harsh environmental conditions, leading to the adoption of mechanized construction methods to maximize efficiency and ensure timely completion [4]. - The project has already facilitated the transmission of 26.95 billion kWh of electricity to 26 provinces, indicating its significant role in the national power grid [7]. - Gansu aims to plan for 2-3 additional external transmission channels to be included in national planning, further transforming energy resource advantages into economic benefits [7].
