“The national electric power supply and demand nervous. In power load up, power generation gap increases, the proportion of electricity by increased, in Beijing this summer will also be the power supply and demand contradiction.” Beijing electric power company spokesman, said Beijing is expected to power grid zhao4 yun2 this summer in electrical load biggest 18.5 million kw to 19.1 million kw, a 2010 growth between 11.04% to 14.64%, among them, air conditioning cooling load account for 40%.
Beijing is typical of the power grid, by more than 78% of the electric power resource to other provinces and cities, therefore, in conveying the external power supply shortage or extremely bad weather condition, Beijing power grid will face the problem of power supply gap.
At this summer’s overall power gap and local area in the weak link, the electric company compiled the orderly power supply management scheme and pull way limiting power ordinal measures, the city government has already been reported by the relevant department for examination and approval. Zhao4 yun2 disclosed.
If appear continues the high temperature high humidity and extreme weather, or destruction of external force in the accident, and the relevant department damaged power supply facilities will carry out the wrong peak, peak orderly power solutions and pull way limiting power measures. But, and residents will be priority is making sure “electricity.
The Northwest into the the weak link
The summer heat, electricity use surge, residents in Beijing rising power load, the most serious substation overload-white fang changping district 110 kv substations but it can no longer bright red flags.
The substation responsible for more than residents in 30 connects center provide electricity security. Last summer, the continuous wet high temperature weather, residents in white fang, electricity substation overload, equipment for high temperature operation serious 2 hours 28 minutes, had become a Beijing area overload serious one of transformer substation.
“This year won’t appear of last year, connects center area power supply can worry about.” Changping power supply company director of technology production Xiao Wan Fang said with a laugh. White fang substation after modification, the substation capacity to 150 million current-voltage, power supply has increased 138%.
According to information, the Beijing municipal power company new and expansion this year of 110 kv substations and above 20 seats, the project implementation greatly alleviate the light, connects center, shangdi, grass bridge in the provinces of power supply pressure, basic satisfy these areas the growth of power demand.
However, Beijing power grid still has some concerns. “Due to the power grid construction influence, the northwestern Beijing area by insufficient power allocation, this also is Beijing power grid in the network structure the weakest link in this summer, the power supply situation.” Zhao4 yun2 said.
Electricity saving should start to reduce standby
“Beijing in surrounding areas for support and, at the same time, to start from me, save electricity reasonable of electricity.” Beijing municipal development and reform commission officials say. Last summer, Beijing clearly requires public institutions and develop power saving of the first demonstration role. Strict control indoor temperature, air conditioning room temperature shall not be lower than the summer set and 26 degrees Celsius, advocating set to 27 degrees Celsius.
For the average household saving electricity, experts court, residents are not at home, should turn off the electric equipment switch, reducing standby power consumption. Also, try to avoid more powerful electric appliance and at the same time, to ensure safety.
