"This year, Sichuan has arranged 8 billion yuan to speed up the transformation of the power grid, so as to avoid the phenomenon of power cuts that still occur in the era of power surplus," the relevant person in charge of the Sichuan Electric Power Company told reporters recently.
In the surplus era, the power-saving re-enactment of the gates was followed by the mass of power stations, and the once-deficient Sichuan power was effectively alleviated, and even this year there was a surplus. According to estimates previously announced by the relevant departments, Sichuan will have a surplus of 6 billion kWh of electricity this year. However, contrary to the residents' expectations, since the high temperature in July, many regions have once again had a power cut.
According to the reporter from the Chengdu Electric Power Bureau, in the recent morning peaks and evening peak hours, except for the outer ring areas such as Huayang and Xipu, the urban areas such as Yulin, Pulp Wash Street and Supo have been cut off. According to the dispatching center of Chengdu Electric Power Bureau, if the high temperature is continued in the near future, the power load is overrun, and there is still the possibility of power cut.
The power grid is embarrassed for the reasons for power cuts in some areas. The person in charge of the Chengdu Electric Power Bureau said that in addition to the power failure, the peak load of the power supply is too large, and the power cut is to ensure the safety of the power grid.
It is reported that in July, in addition to the short-term cooling in the middle of the day, the weather has continued to be high temperature, the residents use electricity to climb, the load of Chengdu power grid has repeatedly exceeded the limit. The load in the highest time of the day has reached nearly 4 million kWh, setting a record high. On July 16, the maximum load reached 3.427 million kilowatts, and the daily power was 65.92 million kilowatt hours, which was 21.5% higher than the peak load during the peak summer season last year. The maximum power increased by 20.6%, and the equipment for heavy-duty and overload operation of the power grid increased significantly. In mid-July, there were eight heavy-duty and overloaded main transformers of 220 kV substations in Chengdu, accounting for 50% of the total. At the same time, there are 23 heavy-duty and overloaded main transformers of 110 kV substations, accounting for 33% of the total, while the urban 10 kV heavy-duty and overloaded lines are close to 40. In the Supo substation, two large 40,000 volt-ampere transformers, under the pressure of the sun and high-load operation, the transformer temperature was as high as 78 °C, and once it broke 85 °C, the transformer would be self-contained due to excessive temperature. Stop running. Since two large transformers are responsible for the electricity consumption of tens of thousands of residents in the Huangtianba-Qingjiang East Road area of ​​the Chengxi area, once they are out of service, they will cause even more power outages. As a last resort, only part of the area to cut power, reduce the load, ensure equipment safety and the normal operation of the grid.
The 8 billion speed-speed power channel reporter learned from the Sichuan Electric Power Company that in order to expand the power grid and ensure residents' electricity consumption, this year, Sichuan has arranged 8 billion yuan for the transformation of the power grid. The power supply units in the province have also compiled a power-limiting plan for large users, which will decompose the power load that needs to be limited to each household. In the overload of the power grid, power shortages, especially late peaks, the relevant enterprises will be arranged to actively reduce the auxiliary production load, avoid the peak production and use of electricity, and arrange the enterprise rotation check at the peak of power consumption, and will be a class of non-continuous operations. The mid-shift arrangement of the production enterprises and the second-class production enterprises is to produce electricity in the middle of the night. In addition, high-energy-consuming enterprises are also scheduled to make electricity production at regular intervals.
The relevant person in charge of the Sichuan Provincial Economic Commission also introduced that as early as June 19, the provincial economic commission organized 1,250 enterprises in the province to avoid peaks in peak hours, and the peak avoidance capacity was over 1.2 million kilowatts. The current power bottleneck mainly occurs during the evening peak period, with a high load, and the gap is about 850,000 kilowatts. The company avoids peaks and can guarantee the electricity consumption of residents in the province. From the whole year, Sichuan's electricity will still have a certain surplus.
It is reported that in the first half of this year, the cumulative power generation in Sichuan Province was 45.8 billion kWh, an increase of 10.1%. The cumulative power generation of the main network was 34 billion kWh, an increase of 12.05%. On July 17, the province's power generation reached 303 million kWh, the highest level in history. It is expected that in the second half of the year, especially during the wet season, the annual electricity consumption will have a surplus of about 6 billion kWh. In view of the trend of surplus power in Sichuan, because electricity is a special energy product that cannot be stored, Sichuan will still mainly consider the consumption of the region, and will strengthen the integration of the power industry with other industries, and lengthen the industrial chain of both sides, while extending the high. The industrial chain of energy-consuming industries will strengthen the direct supply of electricity and pilot a path to develop a circular economy. In addition, strengthen the network connection with East China and other power grids, purchase electricity during the dry season, output power during the wet season, solve the problem of “more and less†in Sichuan's power flood season and low dry season, and let the Sichuan power industry move toward a benign development path. .
