The total investment of NEA in 2020 is about 74.6 billion yuan
"New infrastructure" is not a new concept. Compared with the "traditional infrastructure" represented by "tiegongji" and real estate, "new infrastructure" has been given a new scientific and technological connotation. According to the definition of CCTV's Chinese international channel, "new infrastructure" refers to the infrastructure construction at the technology end, mainly including 5g Infrastructure, UHV, intercity high-speed railway and intercity rail transit, new energy vehicle charging pile, big data center, artificial intelligence, industrial Internet and other seven fields, involving communication, power, transportation, digital and other key industries of social livelihood.
At the beginning of the new year, the two sessions of the national local people's Congress have been held successively, and the work reports of local governments have been issued successively, and the work reports of the governments of all provinces, cities and autonomous regions in 2020 have been published successively. Among them, the work reports mentioned energy and electricity for many times, and the key work involved reform, electricity price reduction, clean energy consumption and other relevant contents in the field of energy and environment. In this paper, the government work report in 2020 related to the energy and environmental industries are excerpted for reference.
On February 26, Mayor Guo Jianying of Baoding city and leaders of the high tech Zone came to Baoding National High tech Zone University Science and technology park to guide Xinyuan green net company to return to work and production, accompanied by main leaders of the company. During the process, Mayor Guo had a detailed understanding of the company's resumption of production, epidemic prevention plan, office disinfection, staff temperature measurement, medical materials storage, etc., and listened to the company's work reports on product field, operation, planning and conception, etc. When it is known that there is a shortage of office space in the enterprise, it immediately instructs the municipal government and relevant units in the park to coordinate and support it. At the same time, it affirms the work of Xinyuan green network company, points out that it is necessary to adhere to the "two hands" of epidemic prevention and control and resumption of production, further implement various prevention and control measures in place, and effectively guarantee the health of employees.
The spring breeze has sounded the new gate, the spring rain has moistened the new grand wish, the spring thunder has awakened the new ambition, the spring flower has decorated the new year's warm, the new year arrived, the new source green net sends the new year's greetings to the leaders at all levels, the friends from all walks of life and all the staff, and passes on our blessing to your family through you.
The 2018 National Conference on prevention and control of electricity theft was successfully concluded in Chengdu. The 2018 National Conference on prevention and control of electricity theft was successfully held in Chengdu, Sichuan Province from May 10 to 11. Beijing Xinyuan Green Grid Energy Saving Technology Co., Ltd., as the first professional power grid line loss management unit in China, was invited to attend the meeting and achieved excellent results.
This phenomenon often occurs after the technical transformation construction in the substation area. The main reason is that the corresponding relationship between "transformation and household" in the substation area is not clear. Because most of the low-voltage lines in the urban area are buried cables, and the route of the lines is relatively concealed, but the original cables in the old area have not been labeled or updated for some reasons. Once the tables of the new public transformer need to be changed, it is easy to fail to correctly distinguish the subordination between the distribution transformer and the household table due to incomplete original data or unclear cable identification.
Combined with the collection of failed households and long-term zero degree households, regularly carry out anti stealing and default electricity use inspection, focusing on the general survey of the business and catering industry in the high loss area, especially for the users with large electricity and the users with sudden increase and decrease of electricity, and timely stop and strictly punish and rectify the default electricity use and stealing found on site.
(1) Different phases of current and voltage (three-phase current line and voltage line are connected with different phases, for example, phase a voltage line is connected with phase C current line, and phase C voltage line is connected with phase a current line.) (2) The polarity of the current is connected reversely. When the primary line is connected from P1, S1 is the current incoming line and S2 is the current outgoing line. When the primary line is connected from P2, S2 is the current incoming line and S1 is the current outgoing line. If one or two phases are connected reversely, it will lead to the reverse running of the meter, resulting in negative loss (if all three phases are connected wrongly, it will lead to no calculation). The display on the meter is "- ia", "IB" or "- IC". (3) Due to the virtual connection of the secondary voltage line, the meter is under / out of voltage, resulting in less / no power.
In the operation and maintenance software of power consumption information collection, after the public substation area meets the modeling conditions and successfully establishes the line loss model, the station area where the line loss rate of the station area cannot be calculated in the statistical period is the "not calculated" station area. The causes and solutions are as follows:
Technical line loss includes: 1. Loss in 35kV and above transmission line; 2. Loss in main transformer of step-down substation; 3. Loss in 6-10KV distribution line; 4. Loss in distribution transformer; 5. Loss in reactive compensation equipment; 6. Loss in low-voltage line; 7. Station power loss in substation; 8. Loss in current, voltage transformer and secondary circuit ; 9. Losses in the grounding wire and electric energy meter.
