Like a piece of jade, set deep in the Cardamom Mountains. On the dam of the power station, the words "Developing hydropower to benefit the people" written in Chinese and Cambodian are particularly prominent. This hydropower station, invested and constructed by China Huadian Corporation Limited, has been in continuous safe production for over 4300 days, with an average annual power generation of about 1 billion kilowatt hours, contributing more than 10% of safe, stable and reliable electricity to Cambodia annually. Recently, reporters visited the Gogong Province in southwestern Cambodia to visit this hydroelectric power station that has been in operation for more than 10 years, to see how it safeguards the lights of Cambodia's homes and contributes to the strong friendship between China and Cambodia. Ensuring stable power supply and reducing electricity costs. In August, during the flood season of the Eresai River, the hydropower station duty officer Yang Weiguo began inspecting the dam early in the morning. Now is the critical period for flood prevention, and there must be someone on duty 24 hours a day, "he told reporters." The current water level is 107 meters, and if it exceeds 108 meters, flood discharge is required. "Yang Weiguo said that the duty personnel need to post two short-term weather forecasts in the work group every day, and release water information such as dam water level, unit load, and dam inflow every hour, and make preparations in advance based on meteorological forecasts. If the rainfall is particularly heavy, emergency plans should be activated. According to the forecast, there will be heavy rainfall soon. We have prepared sufficient flood prevention materials, inspected and maintained backup power sources such as diesel generators, flood discharge facilities, satellite phones, etc., to ensure safe flood control, "said Yang Weiguo. Liu Xinxi, Executive Director of China Huadian Elesai Downstream Hydropower Project (Cambodia) Co., Ltd. (hereinafter referred to as "Elesai Company"), stated that before the Elesai Downstream Hydropower Station was put into operation, 20% of Cambodia's national electricity consumption relied on heavy oil power generation and imports, which not only had high costs but also caused pollution, seriously restricting local economic and social development. The downstream hydropower station of Elesai plays a significant role in ensuring local electricity consumption and reducing electricity costs. More than a decade ago, electricity in Gogong Province relied on imports. ”Wu Xitian, a project translator who lives in Gogong Province, said that Elesai Company has installed a 32 kilometer transmission line from the hydropower station to the city center of Gogong. "In recent years, there have been more factories in Gogong Province. Now there are few power outages, and electricity prices have dropped a lot compared to before. With stable power supply, many of us have purchased air conditioning and other electrical appliances in our homes. We are very grateful to Chinese companies." Cambodian Senate Chairman and former Prime Minister Hun Sen once inspected the hydropower station and called it a "precious gift sent by the Chinese people. Deputy Governor of Koh Kong Province, Shen Hong, said that Koh Kong Province is a major fishing province in Cambodia. With sufficient and cheap electricity supply, local fishermen can freeze and deeply process their caught seafood, sell it to farther places, and increase income. "The benefits brought by hydropower stations are long-term. The implementation of Chinese standards emphasizes technological innovation and enters the centralized control center of the downstream hydropower station in Elesai. The huge electrical main wiring simulation screen is displayed in front of us, and the operation status of the units, reservoir water level, power generation load, and other information are clear at a glance. This system can remotely monitor the operating status of hydroelectric power plant units and prompt for equipment abnormalities, "said Yang Shenghui, the head of the production technology department of Elesai Company. Arriving at the hydropower station testing center, an operator is conducting equipment testing. He filled the transformer sampling oil with nitrogen gas, placed it in an oscillator, heated it to 50 degrees Celsius, oscillated and let it stand, and took out the oscillating gas and injected it into the chromatograph. By analyzing the test results, the health status of the transformer can be accurately determined. Yang Shenghui said that this equipment can detect whether the transformer oil contains other impurities, which facilitates timely detection of problems and extends the service life of the transformer, ensuring the healthy operation of the equipment. Yang Shenghui told reporters that regular testing of special equipment is related to the safety of personnel and equipment in hydropower stations, but Cambodia lacks relevant technical standards and requirements. In 2016, the project built the earliest hydropower station testing center in Cambodia according to advanced Chinese standards. At present, the hydropower station testing center has covered more than 90 testing projects such as relay protection, generators, transformers, circuit breakers, etc., and also provides services to other Cambodian Chinese power companies. We bring Chinese technology to Cambodia to strive for providing high-quality clean electricity and lighting up people's beautiful lives. ”Liu Xinxi stated that safety production is crucial. The company attaches great importance to maintenance and technological innovation, and has obtained 8 utility model patents. At 7 pm in the evening, a conference room at the hydropower station was crowded with people, and local employees were learning Chinese through video conferencing. In order to cultivate composite operation and maintenance talents for hydropower stations, Elesai Company and Guangxi Vocational and Technical College of Water Resources and Electric Power have jointly held multiple "Chinese+Hydropower Vocational Skills" training courses. The training course lasts for one year and mainly focuses on online training, covering various courses such as Chinese language, hydropower vocational skills, etc. Lin Saida, the auxiliary duty officer for hydropower station operation, insists on attending training classes 3 to 4 times a week. I am familiar with professional knowledge such as voltage, frequency, and power generation, and my Chinese expression has become more fluent, "Lin Saida told reporters. She is working hard and hopes to one day be able to handle the difficulties encountered in projects like her Chinese colleagues. Training has changed my career choices. ”Project translator Pan Na said. Panna used to work as an electrician in Phnom Penh and started learning Chinese after arriving at the downstream hydropower project in Elesai. Through hard work, she became a full-time translator. "Working here has improved my income a lot. I hope to continue to learn, accumulate more knowledge and experience, and become a versatile person." Organize the Cambodian training class of the "the Belt and Road" Energy Institute, create a "Guishui Workshop" jointly with domestic universities to train electric power technicians, hold a "Huadian Night School", provide "Silk Road" scholarships, and organize outstanding Cambodian employees to visit China. Rich training programs have enabled a number of Cambodian employees to grow up in hydropower stations and take important technical management positions, and the feelings of Chinese and Cambodian employees are increasingly harmonious. The downstream hydroelectric power station in Elesai not only drives local employment, but also provides opportunities for people to learn about the world's advanced hydroelectric technology, which is expected to enhance Cambodia's ability to independently build, operate, and maintain hydroelectric power stations. ”Shen Hong said.
