Hulunbuir is located in the golden latitude of ice and snow at 47 to 53 degrees north latitude, spanning the Inner Mongolia Plateau, the Great Khing'an Mountains and the Songnen Plain, with more than 200 days of ice and snow a year. The naturally formed snow resort, profound ice and snow sports heritage, and unique ice and snow culture have made Hulunbuir and the 14th National Winter Games (hereinafter referred to as the "14th Winter") form a "destined" ice and snow covenant.
From meeting to farewell, in this 11-day "Frozen", as an important energy supply guarantee enterprise in eastern Inner Mongolia, Huaneng Mengdong Company used a 70-kilometer "warm channel" to deliver warm currents to the white grassland, lit up the bright lights of northern Xinjiang with a steady stream of current, and used a smart "black technology" to let athletes feel the warm winter sun...... Continue to inject surging momentum into this ice and snow sports event.
Embrace good expectations
"We must keep in mind the mission, live up to the trust, and make every effort to win the '14th Winter' supply guarantee battle with the greatest confidence, the highest standards, the hardest measures, and the strongest support capacity, and contribute to the Inner Mongolia Autonomous Region's success in the '14th Winter' event. Jiang Peng, Secretary of the Party Committee and Chairman of Huaneng Mengdong Company, repeatedly emphasized at the "14th Winter" special work meeting on supply assurance.
Establish a special class for guaranteeing supply, prepare a supply guarantee plan and emergency plan, refine and sort out the work plan for key tasks, and clarify the division of responsibilities, main tasks and schedules...... Huaneng Mengdong Company's "14th Winter" supply guarantee and overall planning work was carried out in an orderly manner. At the same time, the company dispatched special personnel to grasp the dynamics of the event and the arrangement of activities in a timely manner, comprehensively do a good job in the energy guarantee of the "14th Winter", and complete 68 key tasks of supply guarantee with high quality.
Since the start of the "14th Winter", the four units of Huaneng Mengdong Company, Yimin Coal and Power Company, Hailar Thermal Power Plant, East Hailar Power Plant, and Zhalantun Thermal Power Plant have comprehensively upgraded their supply standards, vigorously and reliably supplied electricity and heat, and ensured that the generator sets should be opened as much as possible, coal production per ton of coal must be competed, the heating system is running stably, and the fuel is transported efficiently and smoothly, so as to go all out to help the success of the sports event. In view of the large range of supply, low temperature and the peak of electricity consumption during the Spring Festival, Huaneng Mengdong Company linked up and down and dispatched 30 technical experts to carry out a dragnet survey of the heating system of various venues and reception hotels in the "14th Winter", and eliminated 35 hidden risks in a timely manner.
In terms of ensuring the heating supply of important areas such as competition venues, Huaneng Mengdong Company has formulated a "one stadium, one case" supply guarantee plan, and key posts are on duty around the clock, and 22 emergency drills such as large-scale heat outage and main network leakage have been carried out. The three emergency support groups composed of technical backbones provide support services at many important points such as heat exchange stations, reception hotels, and competition venues, and the thermal customer service personnel are online 24 hours a day, so that "the equipment is managed, and there are people watching everywhere". During the "14th Winter" period, all 84 "guaranteed heat exchange stations" under the jurisdiction of Huaneng Mengdong Company operated smoothly, with a heat supply of 2,263,600 GJ, successfully completing the task of heating guarantee. The organizing committee of the event specially sent a letter of thanks to give high recognition and praise to the work of guaranteeing supply.
Embrace the test of ice and snow
"Today's temperature has dropped to minus 35 degrees Celsius, heavy snow, tomorrow is the opening ceremony of the '14th winter', each team should continue to strengthen the maintenance and inspection of key equipment to ensure the safe and stable operation of heating equipment. "One by one, the supply guarantee instructions were issued from the dispatch center of Huaneng Mengdong Company to 28 supply guarantee teams and nearly 500 staff members on site.
"The temperature is minus 36 degrees Celsius, the northwest wind is greater than level 6, the snow thickness is 90 centimeters, the visibility is less than 20 meters, and the inspection equipment is ...... stable operation," Liu Weijun, a special engineer of the heat network of the power generation department of Yimin Power Plant, stood in the knee-high snow to carefully inspect and record the inspection of long-distance heating pipelines from Yimin Power Plant to Hailar City. This 70-kilometer-long heating project in the world's alpine region is responsible for the heating of 15.28 million square meters in the central urban area of Hulunbuir. In order to ensure the safe and stable supply of heat during the "14th Winter", Yimin Power Plant set up a vanguard team of party members to increase the frequency of inspections and shorten the inspection interval to protect this heating lifeline.
The "14th Winter" was held during the Spring Festival holiday, and the load of the power grid was generally low. In order to ensure the safe and stable supply of electricity, as the most important power supply point in Hailar District, Hailar Thermal Power Plant maintains stable load output on the one hand, and cooperates with the power grid to deepen the consumption of new energy and do a good job in deep peak regulation. During the "14th Winter" period, the plant completed a total of 19.87 million kWh of peak regulation, giving full play to the role of thermal power units as a "ballast stone".
Cang Lifeng can be confident. In view of the complex situation of severe cold weather and wide distribution of supply guarantee units, Huaneng Mengdong Company adheres to the idea of "a game of chess", optimizes production organization, establishes a mechanism of "rapid linkage of production, loading, transportation and storage integration", efficiently connects all links of transportation, mining, transportation, discharge and supply, improves coal production efficiency, and ensures that sufficient "rations" are prepared for key supply users. During the "14th Winter", the average daily coal output reached 85,400 tons, ensuring a steady stream of "Wujin" burning red "guaranteed supply" furnaces.
Pour out your wisdom and bring out the warm winter sun
In the case of guaranteed heat source, how to make athletes and tourists live more comfortably has become the goal pursued by Huaneng Mengdong Company.
In the smart heating hall of Hailar Thermal Power Plant, the water supply and return temperature of 15 "Fourteenth Winter" reception hotels are displayed online in real time. With just a few clicks of the mouse, the staff will enter the command, and the temperature of the house will change accordingly.
"In the past, due to the backward monitoring methods, the uneven distribution load at the end of the thermal pipe network, and the difficulty in regulating the pressure and flow, led to the occurrence of 'undersupply' and 'oversupply' from time to time. Zhang Dongxue, chief dispatcher of the heat network dispatching center of Hailar Thermal Power Plant, said, "Now, through the smart heating platform, we can implement remote control of heating balance for the first time, and realize the on-demand supply of flow and temperature while eliminating the need to manually adjust the balance valve." ”
The smart heating system put into operation by Huaneng Mengdong Company effectively integrates "smart heating" into the production process through a management and control platform, a data center, and a monitoring system network. From the automatic operation of the boiler to the intelligent balance of the pipe network, and then to the intelligent monitoring and adjustment of the entrance valve and indoor temperature, the integrated heating supply of "source-network-household" has been formed, and the goal of "balanced transportation and precise heat supply" has been achieved, and the heating quality has been significantly improved.
In addition, during the "14th Winter" supply guarantee period, the company's coal whole-process integrated management and control platform, 5G + mining driverless trucks, intelligent inspection robots and other "black technologies" came into battle to empower the supply guarantee, so that the supply guarantee work from the crowd tactics of fighting physical strength and time to the wisdom of fighting technology and efficiency, realizing the transformation from "will" to "smart" supply.
Say goodbye to the feast of ice and snow, and the struggle will not stop. During the "14th Winter" period, Huaneng Mengdong Company has completed a total of 787 million kWh of power generation, 939,000 tons of coal output, and 806,000 tons of coal transportation, successfully completing the glorious mission of ensuring the energy supply of the "14th Winter". On the new journey, Huaneng Mengdong Company will continue to improve its energy security and guarantee capabilities, strengthen its energy supply guarantee responsibility in the three major fields of power generation, coal and heating, and strive to write a new answer sheet for the high-quality development of energy supply guarantee in the northern Xinjiang of the motherland.
