Do Not Use The Rule To Develop UHV And Nuclear Power

- Oct 21, 2018-

On March 3, Liu Zhenya, member of the Standing Committee of the National Committee of the Chinese People's Political Consultative Conference and State Grid, published a signed article "Developing UHV Power Grid to Crack the Haze" in the People's Political Consultative Conference newspaper, and proposed that accelerating the development of UHV is the fundamental solution to the problem of smog.

On the same day, the first plenary meeting of the Hunan delegation decided to propose to the Second Session of the 12th National People's Congress in the name of the whole delegation, calling for the early launch of the inland nuclear power project such as the Taohua River. This is the Hunan delegation following last year. Once again, in the name of the whole delegation, it is proposed to start the inland nuclear power project as soon as possible. It is suggested that the development of inland nuclear power will become a necessary measure to improve the quality of the atmospheric environment and to control atmospheric haze such as PM2.5 in North China, the Yangtze River Basin and Central South China.

On the same day, He Wei, a member of the National Committee of the Chinese People's Political Consultative Conference and chairman of the China Guangdong Nuclear Power Group, said that nuclear power has an obvious effect on the control of atmospheric pollution.

In summary, the three messages mainly express the following meaning: the development of UHV and nuclear power can solve the dilemma of managing haze.

The arguments of its viewpoint can also be summarized: UHV can reduce the layout of thermal power plants in the eastern and central regions through “remote transmission” to reduce pollution emissions; while developing inland nuclear power can improve and control the total coal consumption, and does not exist. safe question.

Let me talk about the background of UHV and inland nuclear power. These two words are hot in the energy circle! One is that the national grid "has been attacking and has never been won", one is that the country does not start, but it is always trying to break the ice. The commonality between the two is that they are all controversial in the industry.

For example, UHV, the current debate on UHV comes from the economic and safety of UHV AC projects, and the construction of a national network of “three verticals, three horizontals and one ring” will break the six proposed by the 2002 electric reform. The design of large-area interconnected power grids, because one of the original intentions of the latter regional power grids is to constrain the “one-size-fits-all” grid structure and separate the transmission and total dispatch functions.

Let's talk about inland nuclear power, which was very clear when China restarted nuclear power after the 2012 Fukushima nuclear accident in Japan. At the end of October 2012, Wen Jiabao, then Premier of the State Council, presided over the State Council executive meeting to discuss and adopt the "Energy Development 12th Five-Year Plan" and discuss and adopt the Nuclear Power Safety Plan (2011-2020) and Nuclear Power. Long-term development plan (2011-2020), the meeting will deploy current and future nuclear power construction: During the “Twelfth Five-Year Plan” period, only a small number of fully demonstrated nuclear power project sites will be arranged along the coast, and no inland nuclear power projects will be arranged. Since then, several central provinces and some nuclear power companies have begun various forms of appeals, hoping to restart inland nuclear power.

After the background is finished, and then the information is connected to the beginning, it is not difficult to understand. But UHV has the same background as inland nuclear power, but the situation is different.

In terms of the treatment of UHV, it has been clearly supported by the top management and the National Energy Administration. On February 12, Premier Li Keqiang presided over the State Council executive meeting to study and further strengthen the regulation of air pollution such as smog, indicating that the first measure is to implement cross-regional power transmission projects. At the same time, the National Energy Administration also proposed to plan and construct 12 Air pollution control transmission channels, 8 of which are UHV channels.

In the case of inland nuclear power, a recent news is that CGNPC applied to the National Nuclear Safety Administration to “transfer the forgings and parts of the main equipment of Xianning Nuclear Power Plant to Lufeng Nuclear Power Plant” and obtained the “consent” reply from the latter, which is considered to be CGNPC. In desperation, the inland nuclear power plant with an investment of over 10 billion yuan has been stagnant. China Guangdong Nuclear Power Co., Ltd. applied for the deployment of project equipment and transferred it from the inland nuclear power plant to the coastal power station. This is considered by the industry as “the short-term restart of inland nuclear power is hopeless”. signal. The Xianning Nuclear Power Plant and the Hunan Taohuajiang Nuclear Power Plant, which the Hunan delegation called for restarting, are one of the inland nuclear power plants that have been approved for construction.

Then, whether it is UHV or inland nuclear power, what is the relationship with the management of haze? The former gives the link that the long-distance UHV can reduce the layout of thermal power plants in the eastern and central regions through “remote transmission” to reduce pollution. Emissions; the latter gives the link to improve and control the total amount of coal consumed, and there are no safety issues.

From this point of view, the two are indeed related to the drive. However, the author thinks that there are still several points to discuss. In terms of UHV, long-distance transmission only transfers pollution from A to B. From the total amount, there is no substantial change in pollution. In addition, the line loss network loss of UHV AC has been controversial. If the power loss is too large, is it worth the loss?

In terms of inland nuclear power, when it comes to controlling the total amount of coal consumption, the main point now is to replace and improve coal consumption with new energy and improve energy efficiency. In fact, in the replacement of new energy sources, the safety of inland nuclear power is highly controversial, and the disposal of nuclear waste is also a difficult problem. Under the premise of not breaking ice, it is the election and the development of wind power and photovoltaic power that are almost uncontroversial. Preferably, after all, the safety of inland nuclear power is the main reason for pressing the "pause" button at the national level.

As a result, the smog of the two seems to be not as closely related to propaganda, or just to make sense. In my opinion, this is more like the appearance of these "difficult" problems after another "packaging". After all, the current people's voices for the control of smog are huge, and it is very likely that they will reach the other side.

But as a bystander, we expect that the development of UHV and inland nuclear power, please do not in the name of cure.
