A hundred years of electric power development history

A century-long history of electric power development;

19 one hundred years of electric power development 1800, Volta invented the first chemical battery 183 1, and people began to get continuous current. Faraday made the earliest generator-Faraday disk 1866, and Siemens made the first self-excited generator with electromagnet 1870.

Using DC power generation for nearby lighting 1879, San Francisco built the world's first commercial power plant, with two generators and 22 arc lamps.

In the same year, France and the United States successively installed experimental arc street lamps 1879. Edison invented the incandescent lamp? 188 1 year, Britain built the world's first small hydropower station,1882;

Edison built the world's first conventional power plant in new york on 1882. Depree Company of France performed a DC generator set with a voltage of 1500~2000V at the Munich World Expo. The electric pump is driven by the 57km line in 1884. 1885 The British made the first steam turbine, and in March 1986, they made the alternator and transformer. The first AC transmission system was established in barrington. The power supply side is boosted to 3000V, and the voltage is reduced to 500V at the receiving end via 1.2km.

The superiority of AC transmission can be seen. 189 1 year, Germany installed the first three-phase 100kW alternator in Lao Fen Power Plant, and transmitted power to Frankfurt through the first three-phase transmission line. 1894, Liagara Falls Hydropower Station was completed.

1896 was transmitted to Buffalo, 35km away, by three-phase AC transmission.

Ending the debate about which is better or worse between AC and DC in 1880.

The century-old history of electric power development in the 20th century is 1903. Westinghouse Electric Company installed the first 5000kW steam turbine generator set, marking the beginning of general steam turbine generator set.

19 16 The first 90km 132kV line was built in the United States 1922, and the first 220kV line was built in California.

After World War II, the United States manufactured and put into production 30, 50, 1955, 1960, 1963, 1970 and 1973 respectively. 1954, Sweden built a 380kV line for the first time, using two split conductors, with a distance of 960km, to transmit the power of Harspranget hydropower station in the Arctic Circle to southern Sweden.

1954 The first nuclear power plant was built in the former Soviet Union, 1973 The French made10.2 million kilowatt nuclear reactor? 1964 The first 500kV AC transmission line was built in the United States? 1965, the first 765kV AC transmission line was built in Canada. 1965, the Soviet union built the first 400kV 470km DC transmission line with a transmission capacity of 750,000 kilowatts. 1970, a 400kV DC transmission line with a transmission capacity of1330 km was built in the United States. 1989, the Soviet Union built the first 1900km AC transmission line with the highest voltage of 1 150kV.

The significance of century-old electric power:

It is a documentary reflecting the history of electric power development in China in the past century, a TV teaching material for building a socialist harmonious society and a conservation-oriented society, and a theme work of patriotism and hard work education.

At the same time, the film provides the public with a window to understand China's electric power industry and its development history, and is an ideal teaching material for vocational education and traditional education of electric power workers. It plays an important role in the cultural construction of electric power enterprises, enhancing the cohesion of employees, inspiring morale and inspiring employees' sense of pride, responsibility and mission.
