UHV technology and system dispute
2022-11-11 13:07:36
In 2011, the State Grid wants to invest 500 billion yuan in the UHV national network. Recently, the State Grid has once again proposed an additional 250 billion US dollars to invest in upgrading the power grid, opening up the dispute between technology and the system. The "cost" of UHV has been several times that of the Three Gorges. engineering. When the Three Gorges Project was launched, it was adopted by the National People's Congress and the CPPCC by secret ballot. Therefore, even if it was questioned today, at least in that year, the decision of the country contained a huge amount of public opinion. Why not let the UHV build an endless debate into a decision-making that encompasses the people's wisdom?
Looking at the disputes over the past decade of UHV, nothing more than two topics. First, it is impossible to avoid the problem of large-scale blackouts caused by the exchange of UHV transmission networks. Second, industry experts and the public are worried that after the national grid has formed a national “one network†through UHV, all power dispatching rights will be owned by State Grid Corporation. Its monopoly position is hard to shake. Therefore, the UHV dispute is nothing more than a dispute between technology and system. Some people will say that the problem of UHV is high-tech problems and institutional problems that are difficult to solve in a short period of time. Even many experts can’t say clearly, can they make democratic decisions?
In fact, in many technical fields, there is a saying that “all technical problems are actually not problems.†It is not unreasonable to put this sentence on UHV. Who can predict UHV technology for decades or centuries? There will be no qualitative breakthroughs, and the blackout problem will not be completely solved. People were full of fear and fear of lightning hundreds of years ago. However, Franklin’s kite experiments proved that the lightning in the sky is the same as the electricity generated by artificial friction. And further invented the lightning rod, eliminating people's fear of lightning. So, in the world, countries with little scientific research in the power field have begun UHV research. Who would dare to say that there will be no "Franklin" in the UHV field?
If the technical problem is not a problem, then what remains is that if the stability problem of the UHV AC grid is well resolved, there will be no large-scale blackouts, and we should not support UHV. Or if the technology of DC UHV has been broken, the national grid will not invest heavily in UHV when it can produce the same effect as the AC grid and will not generate a monopoly of “one national networkâ€. Just as Jiang Zhaozu, an expert on UHV technology in China*, a vice president of the China Investment Association, and the former director of the National Energy Commission of the State Planning Commission, said that he did not oppose UHV scientific research, and opposed the national grid through the UHV grid. monopoly.
Please note that the core of the above two assumptions is that if there is no threat of a blackout, can the national grid be built a “one network†and master the unified dispatching power of electricity. The core of the latter is that if the monopoly effect cannot be produced, the State Grid is willing to invest a lot of manpower, material and financial resources to benefit the people. This is the key to decision-makers and the public to think about and decide, and it is also the key to the UHV problem.
500 billion yuan, or 250 billion US dollars, the State Grid, such a state-owned enterprise can not produce the money even if it issues billions of bonds every year, and the national investment is the taxpayer's money. Since the current direction of technology is unclear, the power grid part of the power system reform has not yet been successful. Why not give taxpayers a little time, wait and see, think again; give power experts a little time to study how to improve the safety of UHV. Coefficients; also give the power system reform a little time, see how to transform and manage the power grid, whether it is completely transformed into a vertical integration of public utilities, or completely market-oriented, let the market decide whether UHV is economical.
In short, UHV is a major event that affects the national economy and the people's livelihood. Every taxpayer should have the right to understand that since the electricity bill is paid, of course, you should know how the electricity is sent, and you should know where the electricity bill you paid has gone. In the absence of clarification of these issues, UHV, can your footsteps be slower?
