Thread Content
Recently, the main substation of the Shaanxi Coal Group Yulin Chemical’s demonstration project for the differentiated utilization of coal to produce new chemical materials was officially handed over. The construction party transferred the main substation to the owner, who will now be responsible for its operation, marking the successful completion of this first milestone in the project. As the world’s largest coal chemical substation under construction, the 110KV main substation for the Shaanxi Coal project began its civil engineering work on July 3, 2020; it took 180 days to complete the main structures of the control and communication building, the GIS room, the capacitor room, and the 35KV substation, with a total construction area of 15,400 square meters. In addition, the project team completed the installation of 4 110MVA main transformers, 1 set of 110KV GIS equipment, 52 sets of 35KV CGIS equipment, 4 sets of 35KV capacitor equipment as well as 35KV grounding resistance devices; 2 sets of 35KV station service transformer systems; and 16 sets of 0.4KV low-voltage distribution cabinets. They also installed a power monitoring system, a centralized control and transmission system, a DC system, a UPS system, etc., and laid approximately 160,000 meters of cables. By December 30, 2020, the main substation was successfully powered up, setting a record for the shortest time required to bring a 110KV substation online from the start of construction to successful power supply.
The 110kV main substation of Yulin Chemical Company, Shaanxi Coal Group, is supplied with power from two sources, both originating from the 330kV Qingshui substation of Yulin Power Grid Company. This main substation serves as the power hub for the entire project, responsible for distributing electricity to the various production areas of Yulin Chemical over an area of 13 square kilometers. The commissioning of the main substation represents the first milestone in Yulin Chemical Company’s demonstration project for the utilization of coal at different quality levels to produce new chemical materials. Hu Zhenhong, the electrical supervisor at the Mechanical, Electrical and Instrumentation Management Department of Yulin Chemical Company under Shaanxi Coal Group, said, “Since the main substation was successfully connected to the power supply on December 30, all electrical equipment in the station has been operating normally. Power is expected to be supplied to various units starting this month, thereby providing a power supply for the 12 regional substations and power stations of the project, and ensuring the successful commissioning of Yulin Chemical’s 1.8 million tons per year ethylene glycol production facility.” ”
