Description
Technical field
The utility model belongs to electric power network technical field, more particularly to a kind of new change power network access system.
Background technology
At present, new chemical materialses Develop Industrial Cluster in Quzhou completes Electric Power Forecasting Based on Artificial beyond original expection
Correct on working foundation, it is necessary to regional power grid development plan is modified according to new Electric Power Forecasting Based on Artificial result.
At present, the strong major network in 500 kilovolts of Quzhou is built up substantially, and 500 kv substation two is possessed altogether：The change of letter peace (2 ×
750000 kilovolt-amperes), Xia Jinbian (1 × 1,000,000 kilovolt-amperes), and by believing peace~Zhi Yan, Xia Jin~bis- imperial two 500 kilovolts of passages
Kept in touch with Zhejiang major network, 500 kv grid rack reliabilities are higher.Root is it was predicted that in " 13 " period, Quzhou chemical industry
New material industry cluster electricity needs is about 579.6MW, according to remote planning, becomes the 3rd main transformer (75 of enlarging for letter peace within 2018
Ten thousand kilovolt-amperes), but in view of the development of Quzhou chemical industry cluster, it is necessary to became the 3rd main transformer (75 of enlarging in 2017 for letter peace
Ten thousand kilovolt-amperes).
Quzhou new chemical materialses industry cluster is concentrated mainly on hugeization block and high-new confession area.Wherein, hugeization block is powered
It is relatively independent, independently planned, be not described herein by Ju Hua companies.High-tech Park is in high-new 110 kv substation and planning
Huang Jiabian (high-new II) is main to be supplied.
220 kilovolts of boat ports, which become, was gone into operation in nineteen ninety-five, and main transformer capacity is 2*150MVA, and 2013 yearly maximum loads have reached
249.28MW, load factor is 83.1%, with high-new section chemical industry load rapid growth, and main transformer load factor will further increase,
Boat port varying duty is up to 266MW within 2015, and load factor is 88.6%, with the operation of the projects such as Hyosung, to main transformer in 2016
Load is estimated will be fully loaded.In addition, the change of boat port is the uniquely upper level power supply of high-new change, if 220kV boats port becomes equipment fault and tripped,
High-new transformer station's no-voltage of entire station can be caused.Therefore, it is necessary to which the Overall Reconstruction for arranging boat port to become in 2017, improves reliability.
Or connect Chongwen change with high-new change.But in the long term, it is necessary to accelerate 220 kilovolts of Chi Ke and become construction, it is therefore desirable to
Arrange Chi Ke to become before the end of the year 2016 to build.
Put into operation postpartum once 220 kilovolts of Chi Ke become, it is considered to draw high-new, first vertical, the China's friend's change belonged to originally in the change power supply of boat port
Gui Chike becomes power supply, and power supply pressure is become to alleviate boat port.Port change of being navigated after adjustment is main rather to be become and high for boat east, deer ring, garden hilllock, day
New garden increases other users newly and become.
