“Double Austria” power experts:

Return to the “battlefield” of Olympic power supply support at the age of 52

At the power supply service center of Shougang Winter Olympic Park, Ding Jianwu, a power expert of “double Olympics”, made a wonderful speech and was interviewed by reporters.

Ding Jianwu, 52, is an old power man with more than 30 years of service. Now he is a senior engineer in the power supply guarantee department of Beijing Power Winter Olympics Office of State Grid, mainly responsible for the technical preparation and power supply guarantee of 2022 Beijing Winter Olympics.

11 years ago, Ding Jianwu participated in the power construction and guarantee of the 2008 Beijing Summer Olympic Games. During the Olympic Games, State Grid Beijing electric power made a solemn commitment of “foolproof” political power protection for the first time.

At an on-site meeting with foreign equipment sponsors, the other party smiled: which Olympic Games in history had no problems with power facilities? All the Chinese power personnel present answered with one voice: “there will be no problem with the power supply guarantee of the Beijing Olympic Games!”

In 2008, they did.

Returning to the “battlefield” of power supply support for the Olympic Games, higher support standards, heavy tasks and infallible mission and responsibility are on our shoulders. Ding Jianwu said that he wanted to fight again and shine again for his beloved power industry.

Ding Jianwu loves sports and often pays attention to major sports events. However, in addition to the competition picture, he focuses more on the point setting of the on-site camera, the layout of power lines, the dress of the field support personnel, etc. he hopes that these details can provide reference for the future Olympic security work.

His colleagues joked and called him “double Austrian”. He said that what supported him all the way was an Olympic feeling.

Walking into the Winter Olympic base camp

As the first park power supply service organization serving large parks in Beijing, Shougang Winter Olympic Park power supply service center actively creates a modern service system of “strong front-end and big back-end”. The center actively handles the whole business from installation consulting to power generation and operation on behalf of customers, realizes “zero errands” for high and low voltage customers in the park, and provides “housekeeper” services from planning and design to operation and maintenance for Olympic customers in Shougang park.

The level of intelligent power equipment of the Winter Olympic Organizing Committee is very high. For the intelligent power well cover outside the Winter Olympic switching station, when the well cover is opened, an alarm message will be sent through the intelligent well cover system to inform the operators to deal with it in time, so as to prevent personal injury caused by the loss of the well cover and the potential risk of the power grid. In the future, the power well cover will cover the whole park to ensure the safety of power cables in the park.

The State Grid carried out intelligent transformation of the Winter Olympic switching station and the distribution room of the Winter Olympic Organizing Committee, and carried out intelligent patrol inspection relying on the patrol inspection robot to comprehensively improve the patrol inspection accuracy; Install intelligent low-voltage switch modules in the low-voltage distribution boxes in the conference center and exhibition hall of the Winter Olympic Organizing Committee, monitor the operating conditions of customers’ end switches in real time, and alarm end faults in time; Distributed energy storage equipment is deployed in the conference center and exhibition hall to reduce the peak and fill the valley as daily energy storage, so as to save customers’ power cost. Important activities are used as UPS to provide uninterruptible power supply.

Through the all-round intelligent power supply guarantee for the Winter Olympic Organizing Committee from intelligent substation – intelligent well cover – intelligent switching station – intelligent distribution room – terminal low-voltage intelligent switch + distributed energy storage, we can further ensure the safe and reliable power supply for the important loads of the Winter Olympic Organizing Committee.
