【TEPCO东京电力是哪个国家的品牌？】

东京电力公司1951年成立，雇员超过4万人，提供日本三分之一供电需求，包括首都东京。

东电企业规模占日本全国电力行业的三分之一，电网主要复盖东京都及周边8县。目前共拥有发电站188所，总装机容量5884万千瓦。其中火力发电站24所，装机容量3303万千瓦；原子能发电站3所，装机容量1731万千瓦；水力发电站160所，装机容量851万千瓦；风力发电站1所，装机容量500千瓦。此外还拥有1542座变电站，总装机容量2亿5095万千伏安。2000年该公司销售电量总计2807亿千瓦时。

此外，作为一家大型集团企业，东电还拥有若干子公司，业务范围涉及设备维护、燃料供应、设备材料供应、环保、不动产、运输、信息通信等行业。

日本东京电力公司2001年建设一座天然气压差发电站，以提高能源利用率。压差发电是指利用液化天然气在低温下变成气体时产生的膨胀能量来发电，即所谓“冷热发电”。

这座发电站在2001年年底动工兴建，2003年初完工，发电功率为7700千瓦。通常，利用管道高压天然气发电时，需要减压。天然气被压缩后，体积会因此而膨胀9倍，产生相当大的能量。天然气压差发电就是利用高压气体在降压时产生的能量发电，亦称“气体直接膨胀方式”。

东电与中国电力界保持着较密切的交往。根据与我原国家能源部签订的定期交流协定，东电自1992年起每年组织两次中国电力企业干部培训班。截至去年底，共培训19批，约300人。

英文翻译：Founded in 1951, TEPCO employs more than 40000 people and supplies one-third of Japan's electricity demand, including the capital, Tokyo. The scale of TEPCO enterprises accounts for one third of Japan's national power industry, and the power grid mainly covers 8 counties in and around Tokyo. At present, it has 188 power stations with a total installed capacity of 58.84 million kilowatts. Among them, there are 24 thermal power stations with an installed capacity of 33.03 million KW; 3 atomic power stations with an installed capacity of 17.31 million KW; 160 hydropower stations with an installed capacity of 8.51 million KW; and 1 wind power station with an installed capacity of 500 kW. In addition, it has 1542 substations with a total installed capacity of 250.95 million KVA. In 2000, the company sold 280.7 billion kwh of electricity. In addition, as a large group enterprise, TEPCO also has a number of subsidiaries, covering equipment maintenance, fuel supply, equipment and materials supply, environmental protection, real estate, transportation, information and communication industries. In 2001, Tokyo Electric Power Company built a natural gas pressure difference power station to improve energy utilization. Differential pressure power generation refers to the generation of electricity by using the expansion energy generated when liquefied natural gas turns into gas at low temperature, which is called "cold and hot power generation". The power station started construction at the end of 2001 and was completed at the beginning of 2003, generating 7700 kilowatts. In general, the use of pipeline high-pressure natural gas power generation, need to reduce pressure. When the natural gas is compressed, its volume will expand 9 times and generate considerable energy. Natural gas pressure difference power generation is to use the energy generated by high-pressure gas when reducing pressure, also known as "gas direct expansion mode". Dongdian keeps close contact with China's power industry. According to the regular exchange agreement signed with the former Ministry of energy of the people's Republic of China, Dongdian has organized two training courses for cadres of Chinese electric power enterprises every year since 1992. By the end of last year, 19 batches of about 300 people had been trained.
