Shandong Power Grid Load the third time this summer has created new high -foreign electricity and clean energy contributing to the "half of the country"

The continuous high temperature brought a significant increase in the load of the power grid. At 13:10 on June 25, the load of Shandong Grid reached 95.988 million kilowatts. This summer, it hit a new high for the third time. Since the beginning of the summer, Jinan, Liaocheng, Jining, Zibo, Dongying, Heze, Texas, Zaozhuang, Tai'an, Yantai and other 10 areas have innovated electricity loads. On June 25, the foreign electricity reached 19.699 million kilowatts, the highest wind power of the wind power reached 9.188 million kilowatts, and the photovoltaic power generation reached 2.4122 million kilowatts. The foreign power and clean energy contributed the "half of the river" when the load peak. The majority of cadres and employees of the State Grid Shandong Electric Power System fight high temperature, fight the heat, quickly respond to customer needs, vigorously promote non -stop power operation, and use their own sweat to exchange tens of millions of "coolness", which shows the responsibility of the "bright messenger".

A strong grid is the basis for ensuring stable summer summer. State Grid Shandong Electric Power adheres to the development of electricity and such as the development of electricity, and does not allow development and other electricity. Since the beginning of this year, Shandong Power Grid has been completed and put into operation. On March 31, the first ultra -high -voltage power grid construction project, the expansion project of the Guangzhou 500 kV substation, was completed and launched, which can effectively meet the demand for electricity and load growth in the economic and social development of Yantai area; on April 16, Qixia 500 kV The expansion project of the substation has been completed and launched, which further optimizes the structure and reliability of the power supply quality and reliability of the eastern power grid of Shandong. On May 25, the expansion project of the Zibo 500 kV power station was completed and launched, and it has run for nearly 27 years. "The old station changing the new face" can effectively meet the rapid growth of power supply load in northern Zibo; on June 20th, Jiaodong ± 660 kV stream replacement station was successfully delivered by No. 4 in the 4th main change, which was a peak of the Qingdao Power Grid. Xia Bao's power supply provides strong support. Today, Shandong Power Grid has developed into the largest high -voltage communication DC network of high -voltage passage in the "three straight and five friends and one ring network", which has laid a solid material foundation for the peak of the power grid.

State Grid Shandong Electric Power firmly keeps the bottom line of the safe operation of the large power grid. They first achieved three 100%of line protection dual -differential rates, dual -lost spirituality rates, and self -investment configuration rates of line protection nationwide. They carried out in -depth old equipment governance work, the equipment was healthier, and the power grid was safer. In terms of control strategy, State Grid Shandong Electric Power deployment State Grid's largest number of Duan'an control, high power deficiency, and non -force voltage emergency control system to achieve millisecond control 2.5 million kilowatts of load, and the grid risk prevention and control capacity has reached a new level. On the professional network major, they first pioneered the three -level protection mode of "qualifying+branch lead+division", which achieved the goal of "user failure goes out, branch line failure". The influence of power outage. "Since the implementation of the third -level protection model of the distribution network, the main line trip rate has decreased by 63.4%, reducing the power outage of 2.31 million times. Minsheng's electricity consumption has been better guaranteed, and the distribution network faults have entered the era of" precise isolation ".

In Dongmu North Village, Gaomi City Economic Development Zone, Shandong Province, the State Grid High -Mi -Power Supply Company workers with power operators took high temperatures to transform 400 kVA's new high -efficiency power distribution transformers of the village's 160 kVA high -energy transformers. Electricity. After the charging fire, the average household capacity of the village was increased to 2.0 kV, which can meet the power needs of local villagers Xia Feng. (Photo by Jia Jiguang)

Effectively use new energy sources and do a good job of new energy consumption provided strong support for the peak of the power grid. Shandong wind power installed machine ranks sixth in the country, and the photovoltaic installation machine ranks first in the country. In particular, the distributed photovoltaic development is rapid. Since the launch of the entire county distributed photovoltaic development pilot development pilot development, there are already 70 counties and districts in Shandong. The total development scale is 36.85 million kilowatts. In the context of large -scale and high -scale new energy access, State Grid Shandong Electric Power has made every effort to promote the high -quality development of clean energy. In response to the original distributed photovoltaic "system without perception and control without means", they took the lead in achieving more than 700,000 households. , 21 million kilowatts full voltage level distributed photovoltaic power generation projects 15 minutes of considerable measurement; the first use of wireless 5G technology to access 10 kV photovoltaic power plant information, the system is the first to control the distributed distributed photovoltaic inverter from the scheduling side Realize smooth adjustment of power generation power.
