Power plants should be far away from residential areas. Is there a specific distance rule?

According to relevant laws and regulations, the Notice on Further Strengthening the Management of Environmental Impact Assessment of Biomass Power Generation Projects in the annex of Document No.82 of the Ministry of Environmental Protection in 2008 pointed out that the environmental protection distance of newly-built reconstruction and expansion projects should not be less than 300 meters.

According to the regulations, this regulation is aimed at biomass power generation projects such as waste incineration power plants: "6. Environmental protection distance: according to the calculation results of unorganized emission source intensity of odorous pollutants (ammonia, hydrogen sulfide, methyl mercaptan, odor, etc. ) Under normal working conditions, and with due consideration of the conclusions of environmental risk assessment, it is suggested that a reasonable environmental protection distance should be taken as the control distance between the project and surrounding residential areas and public facilities such as schools and hospitals, as the basis of planning control. The environmental protection distance of new reconstruction and expansion projects shall not be less than 300 meters. "

power plant

Power plant, also known as power station, is a factory that converts all kinds of primary energy stored in nature into electric energy (secondary energy). At the end of 19, with the growth of power demand, people began to put forward the idea of establishing a power production center. With the development of motor manufacturing technology, the expansion of electric energy application scope and the rapid growth of production electricity demand, power plants came into being.

At present, there are many ways to generate electricity in power plants: thermal power plants, hydroelectric power plants and some power plants that rely on solar energy (photovoltaic), wind power and tides. Nuclear power plants powered by nuclear fuel are playing an increasingly important role in many countries in the world.

A brief history of development

From 65438 to 1970s, Europe entered the era of power revolution. Not only large enterprises, but also small enterprises have adopted a new power-electric energy. At first, the engine equipment only supplied power for the lighting of houses or streets. People call this kind of power station a "residential" power station, which generates little electricity. With the growth of power demand, people began to put forward the idea of establishing power production center.

Edison built a power plant with six engines in Pearl Street, new york, USA in 1882.

The power plant started from DC power generation company. Edison, a famous American inventor, began to build a central power plant in 188 1. 1882, two power plants were put into operation. 1882 65438+ 10, Edison Company of Holland Bridge in London started to generate electricity to supply power to the city cathedral and bridgehead hotel in the west of the post office bridge of Santa Maria Factory.

At that time, the power plant used a steam engine to drive a DC generator. The voltage was110v, and the power could supply 1000 Edison bulbs. At the end of the same year, the power plant of Edison Company in Pearl Street, new york was also equipped with the same type of units. This is the first power plant in the United States, with six engines inside, which can supply power for 6,000 Edison bulbs. Later, a hydroelectric power station appeared on the Fentak River in Petersburg, Russia. The power station was built on a barge to supply power for Nevsky street lighting.

In the early days, there was a long and fierce debate about DC or AC. Edison advocated the use of direct current, and people thought of various ways to expand the scope of direct current power supply, which obviously improved the power supply situation in small and medium-sized cities.

However, for the power supply in big cities, the improved DC power station is still powerless and replaced by AC power station, because for long-distance power supply, the auxiliary voltage must be increased to reduce the power loss in the transmission line, and then the power loss must be reduced through the transformer before it can be delivered to users. DC transformer is very complicated, while AC transformer is relatively simple, with no moving parts and convenient maintenance.

Stanley, an engineer from Westinghouse, developed a transformer with excellent performance. 1886, the company successfully carried out the AC power supply test of transformer. In 1893, Westinghouse undertook the contract to provide engines for the Niagara Falls hydropower project. Facts have proved that only high-voltage alternating current can realize expeditionary power transmission, thus ending the long-term debate between alternating current and DC power supply system, and alternating current has become a universal power supply system in the world.

Early generators were driven by steam engines. 1884, the turbine is directly connected with the generator, which saves the cloud gear device, not only runs smoothly, but also has less wear. 1888, a small turbine was installed in the newly-built Fosbank Power Station, with a rotation speed of 4,800 rpm and a power generation capacity of 75 kilowatts. 1900, a 1000 kw turbine was built in eberfeld, Germany. By 19 12, Chicago had a 25,000 kW turbine generator, and now the largest turbine generator has exceeded 1 10,000 kW, which can run continuously for many years.
