The third indoor intelligent substation in Haimen was completed and put into operation

On June 30, the 110 kV stacked stone transmission and transformation project located in Zhaoliang Village, Haimen Industrial Park was successfully put into operation
.
The project is the third 110 kV indoor intelligent substation built by Haimen Power Supply Company, and the fourth 110 kV substation
in Haimen Industrial Park.
So far, the company's 9 peak summer projects have been fully completed
.

The total investment of the 110 kV stacked stone substation is 65.
44 million yuan, and a new 80 MWA main transformer is built, with 2 110 kV outlets, and 12 10 kV outlet intervals
.
After the 110 kV Xingqiao was put into operation in 2010, it met the electricity demand of Haimen Industrial Park at that time, but in the summer of recent years, the local electricity load was overloaded
.
Since 2013, Haimen Power Supply Company has expanded the capacity of Xingqiao Transformer, built a new 110 kV Yanying Transformer, upgraded the 35 kV Desheng Transformation to a 110 kV substation, and implemented the 110 kV Rock Stack Transformation Project
this year.

"The commissioning of the project has improved the power grid structure and power distribution in the western part of the city, and provided sufficient, stable and high-quality electric energy
for the development of the western region of Haimen.
" Li Qiushi, general manager of the company, said that the 110 kV stone stacking project is one of
the nine peak summer projects implemented this year.
As the pioneer of economic and social development, the company planned in advance, according to the electricity consumption last summer, and at the beginning of the year, it determined 9 peak summer power grid construction projects, with a total investment of more than 150 million yuan
.

The company solved the overload
problem of some substations last summer by building new substations and expanding the capacity of existing substations.
Among them, 2 new substations were built, namely 110 kV Liu Hao and 110 kV stacked stone change; Expand the capacity of 2 substations, that is, the main transformer of 35 kV Kirin Change No.
1 is changed from 10,000 kVA to 16,000 kVA, and the main transformer of 35 kV Wannian Change No.
1 is changed from 6300 kVA to 10,000 kVA, solving the problem
of heavy load of the main transformer of the two substations.
At the same time, the line bending project was implemented, involving the 10 kV Embroidery Garden Line, Qiaoxing Line, Guangfeng Line, etc
.
So far, all 9 power grid peak summer projects of the company have been completed and put into operation, and the implementation of these projects will effectively solve the problem of
insufficient power supply capacity in the northeast and northwest regions.

In recent years, with the advancement of coastal development, a number of projects have settled in Haimen Port New Area, where electricity consumption has risen sharply, but there is only one 110 kV substation and the 35 kV Dongxing substation is mainly heavy-loaded
.
In order to alleviate the local power tension, Haimen Power Supply Company started the construction of the 110 kV Liu Hao power transmission and transformation project in June last year, with a total investment of 63 million yuan
.
Not long ago, the 110 kV Liu Hao change was completed and put into operation, and 1 new 50,000 kVA main transformer was
added.

According to forecasts, the maximum load of Haimen power grid this summer will exceed 770,000 kilowatts, a year-on-year increase of 13.
6%, Li Qiushi said that at present, the power supply capacity of Haimen power grid can meet the overall demand
of the city's summer electricity consumption.
In the next stage, Haimen Power Supply Company will strictly follow the orderly power consumption plan, scientific dispatch, strengthen the protection of power facilities under high temperature, heavy rainfall and other bad weather, ensure that the residents of the city have a cool and comfortable summer, and make every effort to ensure the normal electricity
consumption of enterprises.
