"There are eight transmission lines with ice today, and the ice melting conditions have not yet been reached. A total of 3 communities and townships in Nanming District and Qingzhen City are carrying out transformer capacity expansion ...... to ensure that citizens have sufficient electricityAt 10 o'clock in the morning of February 6, Lin Xuan'an, the commander of the production command center of the Guiyang Power Supply Bureau of the Southern Power Grid, was always staring at the large screen of the production command center in front of the desk. Patrol the information and data of each plate is the most daily and basic work to ensure the safe and controllable operation of the line, and the orderly and efficient operation of the staff.
Since 2021, as the only "post-95" female commander of Guizhou Power Grid Company, Lin Xuan'an, a Hunan sister, has been on duty during the Spring Festival for three consecutive years. During the Spring Festival this year, Lin Xuanan and his team members were still on duty to guard the bright lights of thousands of homes.
The "test" of cold weather
There is a general consensus in the hearts of power supply people: warm weather is a blessing, and continuous low temperature is a test. If there is an important festival with continuous low temperatures, it must be a heavy responsibility and meticulous. The Spring Festival is approaching, and the continuous low temperature weather in Guiyang makes Lin Xuan'an and Chen Fangqi, Zou **, and Deng Ying, who are also on duty, frequently upload and distribute all kinds of production information through system scheduling, and interact horizontally, and strive to quickly deploy all kinds of resources to ensure the reliable operation of the power grid.
The weather data presented by the weather module on the large screen is shared with the meteorological data of the meteorological department in real time, so that we can monitor the freezing weather conditions in the power supply area for the first time. Lin Xuan'an introduced, not only the large screen, but also the weather and meteorological module has also been "implanted" into Lin Xuan'an's personal mobile phone, even if the person is not in the center, he can also grasp the weather situation at any time through the meteorological module data, and he can quickly return to the unit in case of emergency.
When the last round of Guiyang power grid encountered freezing weather, Guiyang Power Supply Bureau quickly launched the first emergency response, and Lin Xuanan returned to the unit as soon as possible after receiving the information through his mobile phone at home.
When freezing weather occurs, Lin Xuan'an's production command center will horizontally cooperate with the Transmission Management Office of Guiyang Power Supply Bureau to set up an expert "1 1" agent duty mode. After Lin Xuan'an found that there was icing on the line through the icing monitoring and alarm data in the production command system "Peak Winter Plate", he immediately notified the staff of the transmission management office to immediately go to the scene to confirm the icing situation on the spot, and simultaneously asked the substation management office of Guiyang Power Supply Bureau to prepare for ice melting in the station, and asked the production command center of the district and county power supply bureau with icing lines to carry out corresponding work preparations. Once the icing line reaches the conditions for starting ice melting, the ice melting work will be carried out seamlessly and in an orderly manner.
In cooperation with the ice-melting operation, with the help of the "virtual commander" of the production command center, the district and county power supply bureaus involved in the icing line quickly locked key users and issued early warning notices for electricity consumption. "Virtual Commander" is a system independently developed by Lin Xuan'an that can quickly summarize line power outages and user data information. "With it, our data briefing, which we used to do in at least an hour, now takes just five minutes. During the period of power supply, we will issue a total of 4 production data briefings in the morning, afternoon, night and throughout the day, so that the overall situation of the power grid production and operation can be well understood and targeted, so as to better ensure the normal production and life of users. Lin Xuanan said.
The large screen of the production command center of Guiyang Power Supply Bureau can not only see the real-time icing value in the icing system at any time, but also supervise the work of the ice melting site in real time. At work, Chen Fangqi always focuses on the on-site operation ** monitoring platform to do a good job of early warning and violation reminders in time.
The "escort" of the lighthouse of wisdom
In order to ensure that every household uses electricity during the Spring Festival, the production command center uses the "virtual commander" to quickly summarize the points with large power supply loads, and coordinate functional departments and district and county power supply bureaus to efficiently carry out transformer capacity increase. On the other hand, the production command center takes the "power supply station" as the unit to establish a close connection with the township streets in the jurisdiction, "through the production command and dispatch, it can efficiently carry out on-site operations such as power grid maintenance and emergency repair, which is based on the powerful 'computing power' behind the production command system." Lin Xuanan said.
In Lin Xuan'an's view, a good command is nothing more than the words "efficient and accurate". In order to defeat the enemy quickly and accurately, the foundation of powerful data computing power is the accurate analysis of abnormal data data of global equipment status.
In Guiyang Power Supply Bureau, for equipment operation and maintenance scheduling and command, there is a set of its own effective combination boxing, which has its own effective combination before the establishment of the production command center. Now, through the production command center, this set of punches is more powerful. The production command center deeply excavates the value of data elements, independently develops 23 lightweight scenarios, provides strong support for the digital transformation of the production domain, and plays an important supporting role in the construction of the overall safety production command system. The data in these scenarios is as large as the location, grade, and load of the substation and line, and as small as the accurate value of each transformer and switch, user information, etc., and is dynamically updated in real time. During the Spring Festival power supply period, through the "Peak Winter Special Report" scenario, it can quickly screen key power supply users, such as heavy overload users, issue early warnings, and carry out operation and maintenance in advance.
If there is a power outage in a certain area of the line to carry out emergency repair, with the support of big data, we can monitor the progress of equipment repair in real time, and realize two '5 minutes', the first '5 minutes' to determine the fault information and quickly transmit it to the production command center of the district and county power supply bureau, and the second '5 minutes' to notify the repair team in place, and at the same time notify the users who may be affected, and do a good job in the last 100 meters of power supply service. ”
In recent years, with the development of integrated digital technology and intelligent algorithm applications, the production command center with higher efficiency and faster disposal has come into being, and the production command center is the big data support center, execution improvement center and equipment monitoring center of the power supply bureau, driven by digitalization and intelligence, to provide reliable guidance and support for the stable operation and efficient development of the power supply system. Through the integration of production command, emergency command and power supply service scheduling, the quality and efficiency of management are improved in an all-round way.
The production command center is 7 24 hours a day rotation, on the first day of the Lunar New Year, Lin Xuanan will also stick to the post with another colleague, and the rest of the team members will be on call around the clock. During the Spring Festival, Guiyang is expected to be dominated by cloudy weather, and monitoring the wildfire situation in the area to which the power grid belongs will become another major focus of Lin Xuanan and his colleagues after the anti-icing work.
In the new year, I wish my parents good health, and our production command center, a 'smart lighthouse', will continue to play a leading role in the application of digital technology and intelligent algorithms, and work hard to achieve the goal of 'zero power outage' and jointly protect the 'warmth' of citizens." Lin Xuanan is full of expectation and confidence.
