Core Viewpoint - The commencement of multiple high-voltage projects in Shandong marks a significant peak in the construction of ultra-high voltage (UHV) infrastructure, aimed at enhancing the power supply capacity and supporting energy transition in the region [1][5]. Group 1: Project Details - The YW UHV project includes the construction of a new 1000 kV Haiyang West substation, expansion of two existing substations, and the establishment of two new 1000 kV lines totaling 1129.8 kilometers [3]. - The Haiyang Xinan nuclear power transmission project involves a new 1000 kV line connecting Haiyang West to Haiyang Xinan nuclear power station, spanning 80.4 kilometers [3]. - The expansion of the Caozhou UHV substation will add a 300 MVA main transformer and several circuit breakers to enhance the station's capacity [3]. Group 2: Strategic Importance - The YW and Haiyang Xinan UHV projects are critical national strategic initiatives that will improve the power grid structure in Shandong, enhance the ability to withstand severe system faults, and optimize resource allocation within the province [5]. - The Caozhou substation expansion is a key component of the Shandong AC UHV ring network, crucial for increasing the grid's capacity to accept external power and ensuring reliable electricity supply to regions like Heze and Jining [5]. Group 3: Management and Execution - To ensure timely project initiation, the State Grid Shandong Electric Power Company has implemented comprehensive management strategies, focusing on high-quality and reliable construction goals [7]. - The company has developed a systematic management framework, including ten specialized plans addressing safety, quality, progress, and technology, achieving notable efficiency in project preparation [7]. - The projects are positioned as the first UHV initiatives to support nuclear power transmission, with a strong emphasis on cultural integration and innovative management practices to ensure safety and quality [9].
