Energy-saving emission reduction contribution outstanding
In recent years, in our country to vigorously manage smog, promote energy-saving emission reduction process, the contribution of the power industry outstanding.
On September 12, 2014, the Action Plan for Upgrading and Upgrading Coal-fired Energy-saving and Emission Reduction (2014-2020) implemented the energy strategy of "saving, cleaning and safety" for coal and power industries in an all-round way, speeding up the upgrading and upgrading and upgrading Efficient and clean development level to make concrete arrangements.
On December 2, 2015, the State Council executive meeting decided to fully implement the ultra-low emission and energy-saving renovation of coal-fired power plants, significantly reducing power generation coal consumption and pollution emissions. The meeting formally raised ultra-low emissions to the national level.
2015 China's history, the most stringent "Environmental Protection Law" promulgated, efficient and clean coal development is imperative. With the increasingly stringent environmental standards, increasing investment in environmental protection, social and business awareness of green gradually increased, China's energy-saving emission reduction has achieved fruitful results.
In recent years, the proportion of large-capacity, high-efficiency, energy-saving and environment-friendly coal-fired units in China continues to increase, and the efficiency of coal-fired power generation continues to improve. By the end of 2015, the nation's total installed capacity of power generation reached 1.525 billion kilowatts, of which 320 million kilowatts of hydropower, 27.17 million kilowatts of nuclear power and 130.75 million kilowatts of grid-connected wind power and 42.18 million kilowatts of grid-connected solar power, up by 0.5 times and 1.5 times respectively over 2010 Times, 3.4 times and 164 times, driving non-fossil energy consumption increased by 2.6 percentage points. In 2015, hydropower, nuclear power, wind power and other non-fossil energy power generation accounted for 27% of the total power generation in China. As of the end of 2016, the ultra-low emission of coal-fired units nationwide exceeded 250 million kilowatts and the energy-saving retrofit reached 190 million kilowatts. Over half of the coal-fired power generation units of the five major power generation groups completed the ultra-low emission retrofit. The nationwide power line loss rate was 6.47% 0.2 percentage points lower year.
From 2012 to 2016, power generation enterprises accelerated the pace of energy-saving and emission-reduction upgrading and upgrading, continuously reduced the energy consumption level and pollutant emission intensity, and continuously reduced the carbon emission intensity. As of 2015, all five major power generation companies completed the "12th Five-Year" emission reduction target ahead of schedule: Huaneng Group achieved full discharge of all the coal mines, a total of 20.69 million kilowatts of units to complete the transformation of ultra-low emissions; Datang Group ultra-low emission units accounted for 25% of the total installed capacity of coal-fired units, the capacity ranks first in the industry; Huadian Group to complete the ultra- And the construction of 38 units, a total of 12,215,000 kilowatts; Guodian accelerate key areas and corporate environmental governance, 21,260,000 kilowatts generating units to achieve ultra-low emissions; the combined State Power Investment Group 7.76 million kilowatts generating units to achieve ultra-low emissions.
Institutional reform further deepened
In March 2015, the "Opinions on Further Deepening the Reform of the Power System" was issued and a new era of electricity reform was opened. Four relevant supporting documents were issued successively. Development and Reform Commission said the release of supporting documents, marking a new round of electric reform began to enter the full implementation stage. As of the end of 2016, 21 pilot provinces (cities) power reform pilot projects have been approved, power supply side reform pilot projects have been approved in 9 provinces (autonomous regions and municipalities), and 32 provincial transmission and distribution tariff reform pilot projects have been fully launched.
In fact, the sale of electricity-side reform is the biggest highlight of this round of electricity reform. The core of the electricity reform is to let go of the competition between the power generation terminal and the sales terminal to form a market-oriented pricing mechanism. In particular, the liberalization of the sale of electricity has a profound impact on the power industry, which is conducive to the marketization of electricity generation and the marketization of electricity prices.
The mixed ownership reform in the power industry and the power system reform are intertwined. The policy of "opening up competitive businesses" has drawn great attention from the enterprises. In 2014, the State Grid Corporation announced that it will release two major areas of distributed power grid-connected projects and electric vehicle charging and switching facilities. In 2015, at the NDRC symposium on pilot reform of mixed ownership reform in power industry, State Grid further proposed the proposal of introducing social investment in the project of pumped storage power station and energy storage device. In contrast, China Southern Power Grid Company took the lead in setting up a mixed-ownership power supply company in the field of incremental power distribution. Five companies, including Shenzhen Power Supply Company and China Merchants Property Co., Ltd., jointly set up a state-controlled Shenzhen Qianhai Shekou FTA power supply company.
It mainly consists of hydraulic supports, hydraulic stations, control systems, and sensors.
Hydraulic support is the core component of the hydraulic support system used in mines, which uses hydraulic cylinders as the support force source,
Capable of supporting huge rock weights in underground mines. The hydraulic station provides a hydraulic oil source,
Hydraulic oil is transported to the hydraulic support through pipelines to achieve support function.
The control system is an important component of the hydraulic support system used in mines, which controls and monitors the hydraulic support through sensors and controllers. Sensors can monitor the status of the bracket in real-time, including support force
The controller controls the hydraulic support based on the feedback data from sensors, such as inclination and displacement, to ensure its stability and safety in the mine.
The hydraulic support system used in mines has advantages such as high support force, good stability, and safety and reliability,
Widely used in underground mining industries such as coal mines, metal mines, and non-metallic mines. With the continuous progress of technology and the continuous expansion of applications, hydraulic support systems for mines will continue to play an important role,
Provide strong support for the safe and efficient development of the underground mining industry.
Become a Power Power Grid technology to follow the steering lead
Since the 18th CPC National Congress, China's power industry has made outstanding achievements in energy conservation and emission reduction, power system reform and smart grid. In the past five years, China's power industry has reached the world advanced level in some fields of energy saving, consumption reduction and environmental protection. China has developed into the largest power power in the world, and the structure and quality of power have been further optimized and upgraded. The mode of development has made continuous progress in practice. The core technology of smart grid, from power generation to electricity technology, has promoted the transformation of China's power grid technology from follower to leader in the world.
