Shiyan, Hubei: Test a high temperature epidemic to ensure safe power generation

Correspondent Huang Dian

Since August, the rainfall of the Battle of Huanglong Beach Power Plant where the State Grid Hubei Hubei is located is only 15.4 millimeters, a 74%decrease from the average annual rainfall. Beginning on August 9, the power plant has a daily power generation of more than 4 million kilowatt -hours, and the water level of Huanglongtan Reservoir has decreased at a rate of 1 meter per day. The current water level has fallen to 230.43 meters. In the case of decreased precipitation and insufficient water from upstream, the power plant adjusts the staining grid in time to avoid vortex in the water inlet during power generation, which affects the efficiency of power generation. The beach power plant fully uses the advantages of rapid and flexible adjustment of the water power plant. Under the dual test of continuous high temperature weather and local epidemic, it is continuously transporting power energy for power grids.

Exciting and careful dispatch, high temperature resistance to prevent flood prevention safety

According to statistics from the Meteorological Observatory of Shiyan City, in 2022, the high -temperature weather of more than 35 degrees Celsius in Shiyan City was 56 days, and the extreme high temperature weather exceeding 40 degrees Celsius was 25 days long.

"This year's high -temperature weather is rare. This is a big challenge for the dispatching of power plants and reservoirs. We must insist on making water -adjustment providers and dispatching each side of the water." Gu Shaofeng, the head of the water transfer squad, said.

Before the flood this year, the waterfall water personnel conducted a comprehensive inspection and maintenance of the 30 telemedicine stations of the river basin and the power system, the GSM and the Beidou satellite dual redundant communication system, and the water rain love monitoring system. Driving for 3,000 kilometers, it lasted for a month, across Hubei and Shaanxi provinces, overcome the impact of the epidemic, and completed the inspection tasks to ensure the safety and reliability of flood control equipment and facilities, and the information transmission was unimpeded.

In July and August of this year, high temperature weather continued, and the electric load of Shiyan City increased sharply, and the four units of the power plant rolled non -stop. In the early morning of August 13, the water level of Huanglongtan Reservoir quickly disappeared from 239.98 meters on the beginning of the month to 235.74 meters, which was nearly 10 meters lower than the water level at the same time. However, the water level continued to decline. Carefully calculate the time when Pankou, Longshou Bay, and Eping, etc. in the basin disappear to the position of dead water.

As of August 31, 2022, the annual power generation of the power plant reached 7145.9 billion kWh, the water utilization increase rate was 15.17%, and the power generation increased by 094.1 billion kWh, which was equivalent to 37,644 tons of coal savings, 93,828 tons of carbon dioxide reduction, and the benefits of water saving and hair saving. obvious.

Bow in the "Iron Army" and strictly lay a solid foundation for security

Since entering the summer, Shiyan City has continuously issued high -temperature red warnings, and the continuous extreme temperatures have repeatedly recorded, and the peak protection responsibilities of power plants have been greatly responsible. After completing the planning of the four units in the first half of the year, the power plant's maintenance sub -field "Iron Army" was immediately put into the peak and summer disappearance.

In August, the epidemic suddenly occurred, and Shiyan's city entered silence. High temperatures that have been over 40 ° C for continuously bring a huge test to power plant equipment. The factory has established party members' assault teams, facing the scorching sun, holding infrared temperature testing instruments, temperature measurement of outdoor switching stations, and organizing responsible persons to compare the diagnosis of the morning, afternoon and historical data to analyze the equipment of the equipment. Operating status to ensure the safe and stable operation of the equipment.

The factory's maintenance branch employees actively eliminate shortages and resolve hidden dangers. Since August, due to the high temperature, the crew of the Huanglong Beach Power Plant has maintained a high load operation, causing the water level of the reservoir to drop rapidly, leaving the unit's water inlet pollution grid split, resulting in a hidden safety hazard that may break the sewage.

It is learned that the entire plant will be shut down from 6 am to 8 am on August 16th, and the "Iron Army" will start to gather at 4:30 in the morning, and arrive at the scene at 5:20. From handling work tickets, before implementing class meetings, to driving charge boats to the sewage waters to carry out demolition, connection, and tightening, until the pollution is adjusted to the best state, the members of the work class will take the boat ashore, sweat soaked them in them. The entire back.

Since entering the summer, the main change of power plant 2 has always existed on the surface condensate. The temperature of the table is inconsistent with the actual temperature, and the actual temperature is low, resulting in too low the main change temperature. Each team organized various teams to conduct on -site observation and testing, and finally adjusted the control method of the main cooler by the seminar to successfully solve the problem of condensation water. At the same time, in response to the current status of low water level operations, the division of labor and cooperation of the team members of the trial class, through drawing analysis, historical trend diagnosis and simulation calculations, and finally determining the best parameters of water levels in different sections to ensure the efficient operation of the unit.

Work together to accurately control the pre -control and keep the power on power without any room.

In 2022, the power plant operated the "small yellow hat" to move rapidly, and carried out the "building to protect the electricity defense line and facing the high 'roasting' inspection" equipment for special patrol operations.

At 21:27 on August 13th, a rapid phone ringtone broke the calm of the central control room of the power plant. "Huanglong Beach Power Plant, this is the provincial adjustment ..." "Okay, we immediately turn on all 4 units." After receiving the scheduling instruction, the power plant operating on duty quickly executed the start -up process. Along with the roar of the water rotor generator rotor, the four aircraft groups of the plant successfully grided successfully.

The factory runs a number of "small yellow hats" in a sub -field wearing a "red vest", holding the temperature measuring instrument, measured the equipment of the 1 and 2 factories and outdoor switch stations, inspect the abnormal heat of the equipment, and timely grasp the switching station belt beltThe operation of the pressure equipment and the display of the instrument, check the drainage ditch, water collection, and factory leakage in the factory area.Hidden dangers and abnormal conditions, ensure the safe and stable operation of the equipment in high temperature weather and the smooth traffic of electricity delivery.Since the notice of high temperature and flood prevention warning of the power plant in 2022, the operating sub -field "small yellow hat" has carried out a total of 62 special equipment tour, discovered and dealt with 27 such as "10kvi reporting 10KVI, section II small current land fault signal", etc.The execution unit started and stop operation 437 times, the start -stop success rate was 100%, and the cumulative transportation power was 146.75 million kilowatt -hours.
