" Power Tianlu " Qinghai sent Tibet power to reach 600,000 kilowatts for the first time

China National Grid Qinghai EleCTric Power Co., Ltd. said on the 27th that the “Power Tian Road” project has completed a large-load test on the transmission and transformation project of ±400 kV Qila DC system. During the test, the power of Qila to Qinghai sent Tibet reached 600,000 kW for the first time.

Known as “Power Tianlu”, the Qinghai-Tibet AC-DC power interconnection project starts from Xining in Qinghai and west to Lhasa in Tibet. It has a total length of 2,530 kilometers and an average elevation of 4,500 meters. It passes through Sanjiangyuan, Hoh Xil and Qiangtang nature reserves. It is one of the 23 key projects in the development of China's western region, and it is also the highest-level DC transmission project at present.

According to China National Grid Qinghai Electric Power Co., Ltd., this year, with the economic and social development of Tibet, the electricity consumPTion has been increasing, and the load on the Tibetan power grid has continued to rise.  According to the analysis of the Northwest Electric Power Control Sub-center, ±400 kV Chaila DC is still the main transmission channel for the Tibet Power Grid. It is expected that the operation of the Chaila DC will be arranged in the end of 2018 and 2019 during the flood season and 600,000 kW.

It is understood that “Power Tianlu” has been pumping a total of 5.418 billion kwh to Tibet since it was put into operation in 2011. Since its commissioning, the project has opened the door for resource allocation, and the Tibet Power Grid, which has been operating alone, has passed through Qinghai Power Grid. Interconnected with the entire northwestern region's power grid, optimized the power supply structure, and solved the long-term power shortage of the central power grid in Tibet.

China State Grid Qinghai Electric Power Co., Ltd. stated that Chaila DC successfully carried out a 600,000 kW heavy load test, which not only created a new high historical load of Chaila DC, but also provided a power supply for the power grid of Tibet Power Grid to improve the power balance of Tibet Power Grid. Strong protection.
