UHV supported Shandong's power grid through the fifth load high

Following the "three consecutive jumps" of electricity load brought about by high temperature, on July 29 and July 30, the power load of Shandong Power Grid climbed again to 69.
328 million kilowatts and 69.
796 million kilowatts, setting a record high
for the fourth and fifth time this summer.
With the help of the 1,000 kV UHV project from Ximeng to Shandong that has just been put into operation, North China Power Grid urgently sent 2 million kilowatts of electricity to Shandong, filling the power gap in time and ensuring the balance of power supply and demand in Shandong Power Grid under peak load, and no power rationing occurred in the province
.

In the past week, many places in Shandong have issued high temperature warnings, and the resulting refrigeration load has continued to rise
.
As of July 30, the electricity consumption of seven prefectures and cities in the province reached a new high, with Qingdao having a power load of 7.
219 million kilowatts, Weifang 7.
441 million kilowatts, Zibo 5.
063 million kilowatts, Dezhou 3.
546 million kilowatts, Heze 3.
533 million kilowatts, Tai'an 2.
838 million kilowatts, and sunshine 2.
734 million kilowatts, all breaking historical records
.

According to data from the State Grid Shandong Electric Power Control Center, during the first three load peaks, the three external power channels of 500 kV Xinliao double line, 500 kV Huangbin double line and ±660 kV Yindong DC reached full load transmission, and continued to transmit 7.
5 million kilowatts of electricity from North China and Northwest China to Shandong, although the power shortage was alleviated, but still could not meet the rising electricity load
.
On July 25, State Grid Shandong Electric Power launched the orderly electricity consumption measures this summer for the first time, organizing some industrial customers, especially large customers in shutdown and elimination projects and high-energy-consuming industries, to carry out peak shifting and peak avoidance production
during peak hours.

"At that time, we predicted that the gap would continue to expand, so we actively applied to the State Grid Corporation of China to start large-load transmission of electricity from Ximeng to Shandong UHV transmission channel on July 27, and gradually increased the load to 2 million kilowatts, making up for the power gap in the first time and avoiding the implementation of orderly power consumption measures
again.
" The relevant person in charge of the State Grid Shandong Electric Power Control Center said that in the future, they will actively strive for more external power in the province according to the load growth, continue to increase the UHV transmission capacity, and ensure the balance
of power supply and demand this summer.

At present, in order to ensure the safe and smooth flow of multiple "lifelines" of foreign power into Lu, State Grid Shandong Electric Power organized more than 200 people to carry out uninterrupted inspections of 4 ultra-high voltage transmission channels and related substations, giving full play to technical advantages, using intelligent inspection robots to measure infrared temperature of substation equipment, and using "drones + manual" inspections to strictly prevent external damage
to transmission channels 。 Local power supply enterprises closely track the power supply and demand situation, continuously optimize the operation mode of the power grid, carry out live detection of power grid equipment, timely carry out dynamic evaluation of equipment status, implement abnormal and serious state equipment safety risk prevention measures, do a good job in power grid security risk analysis, formulate accident handling plans, and ensure that the power grid is safe and controllable
.

It is reported that the Ximeng to Shandong 1000 kV UHV AC project is the first UHV project in Shandong, and the Shandong section of the project was completed and put into operation on June 29, increasing the external power capacity of Shandong Province to 10 million kilowatts
