Hebei Enhances the Capacity to Receive "External Electricity into Hebei" to Ensure the Safe Operation of the Beijing-Tianjin-Hebei Power Grid
July 03 2024 - 3:48AM
Recently, in Xinhe County, Hebei Province, the newly added No.1
transformer of the Xingtai 1,000 kV ultra-high voltage (UHV)
substation was successfully put into operation, increasing the
total transformer capacity from 6 million kVA to 9 million
kVA, State Grid Hebei Electric Power Co., Ltd. stated. This
effectively enhances the capacity to receive power transmitted from
Shanxi, Shaanxi, and other regions, ensuring the safe and stable
power supply in the Beijing-Tianjin-Hebei region during the summer.
Xingtai 1,000 kV UHV substation serves as an
important hub in the Beijing-Tianjin-Hebei-Shandong load center,
undertaking the critical task of "transmitting electricity from the
west to the east and mutual supply between the south and the
north." This year, with the adjustment of the "west-to-east power
transmission" channel, the entire "external electricity into Hebei"
relies solely on the UHV power transmission channels.
According to Wei Zhanning, deputy director of the
UHV Construction Management Center of the State Grid Hebei Electric
Power Construction Company, the newly added No.1 transformer can
not only meet the increasing electricity demand of people's
livelihood and enterprise production during the summer peak season,
but also effectively prevent large-scale power outages caused by
transformer failures, ensuring reliable power supply during peak
hours.
Liang Lihui, the station master of Xingtai 1000 kV
UHV substation, stated, "Since the beginning of this year, the
maximum load we have received from external power transmission has
been 4.35 million kW. After the commissioning of the newly added
No. 1 transformer, the capacity to receive external power
transmission has increased by 3 million kW, which can meet the
daily electricity needs of 1.1 million urban residents during the
summer peak season."
