The use of automated power distribution technology, Youth Olympic Games power security work ended smoothly
The successful hosting of the Nanjing Youth Olympic Games can not be separated without sufficient and reliable power supply. So, the Youth Olympic Games power security work how to ensure that the power supply "foolproof" goal? In recent days, this reporter in-depth interview, and published from August 18, "Electric Liang Youth Olympic Games" series of reports.
In the Olympic Sports Center Stadium A1 substation, the company Green Power Group Suzhou team members Lu Guoqing is checking equipment operating parameters. The tablet in his hand caught the reporter's attention.
Lu Guoqing told reporters that the handheld personal digital terminal is self-developed by Nanjing Company part of the emergency protection platform. The platform uses 4G, WIFI wireless network to build a power transmission command center, on-site command post, information security channel between the transmission channels. "With this personal digital terminal, we can not only receive orders from command centers in a timely manner, but also timely return the operating parameters of venue-side equipment detected by the live-on-line detectors in text, pictures and videos in a timely manner, Support command center decision-making. "
According to reports, the Youth Olympic Games opening and closing ceremonies, a total of 20 mobile power-saving online monitors and 80 personal digital terminals applied to the Olympic Sports Center among the work. During the competition, according to the actual situation, these equipments will be deployed in the key areas of the key competition venues, such as the Olympic Sports Center, Wutaishan Sports Center and so on.
Nanjing, director of marketing Ganhai Qing told reporters that in the past is a point-to-point communication, and now through this platform, power commanding officers in command can grasp all the on-site monitoring points of real-time data.
In the case of failure, power emergency command platform will also provide quick response for the relevant personnel to provide support. Gan Haiqing introduction, with the help of the platform, they digitized the existing contingency plans, and established a database of digital emergency plans, including customer contingency plans, power saving manuals, and typical operation tickets. In the event of failure, power-through personnel through the personal terminal, you can quickly access the relevant plans for the operation of on-site equipment, emergency rescue provide technical support.
"We installed a network camera next to each of the two north and south gensets at the Olympic Sports Center and also used a video motion detection technology to create a no-go zone electronic fence. Once a person or device enters a no-go zone, the guard duty officer immediately receives Alarm signal. "Gan Haiqing said," These devices are like "Clairvoyant", monitoring the object for 24/7 monitoring.
"Once the line and equipment failure, the company distribution network dispatcher can locate the fault point through the distribution automation system, the first time given fault isolation program, the fault isolation in the smallest range, and notify the repair personnel rushed to the scene repair." Wang Chao, director of O & M and maintenance department of Nanjing Company, introduced that "the entire fault point should be controlled within 10 minutes when it is used to isolate and restore power supply, and before the implementation of distribution automation, such a cable fault usually needs more than 1 fault hour."
In fact, as early as 2011, Nanjing company built a pilot automation distribution project. In 2013, the company started the second phase of distribution automation and focused on the Hexi area where Olympic Youth Olympic Games, Youth Olympic Games, International Expo Center and other important green places gathered. At the same time, some other important Olympic Green Power Lines Inclusion, the full coverage of distribution automation has been achieved. This enables the fault location to quickly locate the point of failure, greatly reducing the power outage, in order to improve the reliability of the Green Olympic power supply provides a strong support.
