The Medium and Long-term Plan for Power Demand Side Management (2009?D2013) of Hebei Province was officially released and implemented. According to the plan, from 2009 to 2013, the cumulative power saving of 15 billion kWh will be equivalent to a reduction of 1 million kilowatts of installed capacity (in accordance with the annual operation of the thermal power unit for 5,000 hours), and the capital investment will be reduced by 4.5 billion yuan. According to the goal of saving electricity, it is equivalent to saving 6 million tons of standard coal, reducing carbon dioxide emissions by 15 million tons, and reducing sulfur dioxide emissions by 142,800 tons.
Planning is a guiding document for the province's medium- and long-term scientific, rational, balanced, and energy-saving work. According to the plan, Hebei Province will focus on promoting eight major power-saving projects:
Motor system energy saving project. Focus on the promotion of high-efficiency and energy-saving motors, and basically replace the elimination motor. Vigorously promote the frequency conversion speed regulation, rare earth permanent magnet speed regulation, and automatic control technology to improve the overall operating efficiency of the fan, water pump and compressor system by 10 percentage points, and achieve a power saving of 4.5 billion kWh by 2013.
Double storage project. Expanding the application range of cold storage and heat storage technology in central air conditioning systems and enterprises requiring constant temperature production technology, developing new large temperature difference low temperature air supply air conditioning technology, promoting household ice storage devices and electric heating storage with high energy storage density and small volume Can be new technology. Through the implementation of the double storage project, we will strive to achieve a peak load of 150,000 kilowatts by 2013.
Waste heat and pressure by-product gas utilization project. In the iron and steel enterprises, the blast furnace top pressure difference power generation, dry quenching and converter gas recycling are popularized, and the application of by-product gas power generation technology such as gas, D?D?D steam combined cycle power generation technology is actively promoted. In the cement production line with a production capacity of over 2,000 tons per day, a low-temperature waste heat power generation device will be built.
Electrical energy replacement technology engineering. Use advanced, mature and efficient electrical equipment and technology to replace backward and inefficient other equipment and technologies that consume primary energy (mainly coal and oil) and increase the use of efficient and clean electricity. Optimize energy consumption structure, improve energy utilization efficiency and protect the ecological environment.
Green lighting project. Promote and encourage the use of solar street lights by promoting efficient lighting systems and rare earth trichromatic fluorescent lamps, high pressure sodium lamps, metal halide lamps and LEDs.
Heat pump technology application engineering. Give priority to the development of regenerative water source heat pumps, actively develop ground source heat pumps, moderately develop underground (surface) water source heat pumps, and gradually increase the proportion of heat pump systems in heating and cooling. Strive to build and apply heat pump technology no less than 5 million square meters per year, and reach 30 million square meters by 2013.
Household appliances power saving project. Promote the use of energy-efficient refrigerators, air conditioners, televisions, washing machines, computers, etc., to limit the market circulation of low-efficiency household appliances. In conjunction with the policy of home appliances to the countryside, the residents will be guided to eliminate household appliances that have exceeded the service life.
Reactive power compensation technology engineering. New technologies such as parallel reactive power compensation, reactive power compensation and filtering, and filter bank mode are promoted. After the reactive power compensation equipment is installed in the power grid, the flow of reactive power in the power grid can be reduced, and the power loss caused by the transmission of reactive power of the line and the transformer can be reduced, thereby achieving the purpose of energy saving and loss reduction.

Shijiazhuang City will continue to promote 8000 ç› LED street lights
The reporter learned from the Science and Technology Bureau of Shijiazhuang yesterday that Shijiazhuang City will continue to promote 8000 LED street lights to create a national demonstration city for the city. In order to further promote the development of the semiconductor lighting industry in the city, the municipal government has invested and mobilized 100 million yuan to implement semiconductor lighting application engineering.
The Ten City Wanhao LED Application Demonstration Project is a plan proposed by the Ministry of Science and Technology. If you can successfully declare the LED application demonstration city, it will have far-reaching significance in solving the problems of LED technology, cost and system integration of large-scale production, and establishing a long-term operation mechanism for energy conservation and emission reduction.
Shijiazhuang City has set up a semiconductor lighting leading group with the mayor as the team leader to study and formulate major policies for promoting the use of high-efficiency energy-saving LED lighting products in the city; and actively raise funds to guarantee the funding of demonstration projects and include government investment project demonstration projects. The annual government investment plan; established the investment and financing mechanism with government input as the guide, enterprise investment as the main body and social input as the supplement.
In recent years, Shijiazhuang City has undertaken a series of national and provincial major semiconductor lighting research projects, and the innovation ability and level of semiconductor lighting have been improved. Now it has formed a relatively complete industrial chain such as epitaxial chip packaging applications, especially in applications and products. Innovatively, the resident stone enterprise has developed the semiconductor lighting picture of the opening ceremony of the Olympic Games and the original semiconductor lighting surface light source.
In order to cooperate with the national city of ten cities and millions of LED application demonstration cities, in addition to the promotion of the use of 8000 ç› LED street lights, the city will also promote the use of 2000 ç› LED tunnel lights, 10,000 ç› LED garden lights, 40,000 LED snails Port lamp, 50,000 LED tube, 10,000 LED ceiling lamp. By the end of 2010, the cumulative power saving will be more than 12 million degrees, driving 10% of municipal lighting applications to save 1 billion degrees, Shijiazhuang LED municipal lighting industry scale It has reached 3 billion yuan, driving the output value of semiconductor lighting-related industries to more than 10 billion yuan. At the same time, the use of green and environmentally friendly LED energy-saving products can also reduce the emission of CO2, SO2 and NOX dust by 1 million tons, greatly reducing environmental pollution.

The electrolyte material inside the electrolytic capacitor, which has charge storage, is divided into positive and negative polarity, similar to the battery, and cannot be connected backwards.A metal substrate having an oxide film attached to a positive electrode and a negative electrode connected to an electrolyte (solid and non-solid) through a metal plate.
Nonpolar (dual polarity) electrolytic capacitor adopts double oxide film structure, similar to the two polar electrolytic capacitor after two connected to the cathode, the two electrodes of two metal plates respectively (both with oxide film), two groups of oxide film as the electrolyte in the middle.Polar electrolytic capacitors usually play the role of power filter, decoupling (like u), signal coupling, time constant setting and dc isolation in power circuit, medium frequency and low frequency circuit.Non-polar electrolytic capacitors are usually used in audio frequency divider circuit, television S correction circuit and starting circuit of single-phase motor.
