Today, it was learned from the State Grid Corporation: Recently, the State Grid Corporation’s Northwest to Huazhong Lingbao Converter Station Project and the Genan DC Secondary System Reconstruction Project were successfully completed, and the localization rate of the two engineering equipments was 100%, which indicates that China has already completed The design and construction capabilities of large-capacity and ultra-high-voltage DC projects have reached the international level of similar engineering.
The direct current transmission has only two positive and negative lines, which is less than the AC transmission. Therefore, in theory, it can not only reduce the line loss, but also help the system to be stable, and it can save the line corridor resources and help save the land. However, since the power plant and the user are both AC, the DC transmission must convert the AC power of the power plant into DC, and then convert the DC into AC supply users. Therefore, the converter station is the core of the DC transmission technology.
China's large-capacity and ultra-high-voltage direct current transmission technology applications began with the Gezhouba project and began to be applied on a large scale in the Three Gorges Project, but the key equipment relied on imports. The Lingbao and Genan projects are the pilot projects for DC localization.
It is reported that the Lingbao converter station project is based entirely on domestic construction, and the main equipment is 100% domestically produced. The successful construction of the project marks that China's DC localization has reached a new stage, and it has exemplary and guiding significance for China's independent and independent construction of large-scale DC transmission projects in the future. The Gezhouba-South Bridge 500 kV DC transmission project (referred to as Genan DC Project) is the first trans-regional and ultra-high voltage DC transmission project in China. The renovation project of Genan DC Control and Protection System is the first comprehensive transformation of the control and protection system for large-capacity and ultra-high-voltage DC transmission projects in China. The project uses domestically produced equipment.
At present, the total length of large-capacity and ultra-high-voltage direct current transmission lines that have been built and operated by State Grid Corporation has reached 3826.6 kilometers, and the transmission capacity has reached 6.56 million kilowatts. The total length and transmission capacity of the line are among the highest in the world. The relevant leaders of the State Grid Corporation stated that the State Grid Corporation will accelerate the promotion of UHV work in a planned and step-by-step manner on the basis of improving the transmission capacity of the power grid and strengthening the transformation of urban and rural power grids, and taking the construction of UHV power grids as an important opportunity to resolutely implement the domestic The policy is to fully support the technological upgrading and development of China's electrical manufacturing industry.
Driving in a cold vehicle is never fun. But on a chilly day it takes some time for your engine heater to kick in, which means you have to live with the frigid conditions until the engine has a chance to warm up. Seat heaters are electronic heating elements that install into your seat giving your body warmth on even the coldest days. Unlike conventional vehicle heaters, seat heaters act quickly so there is no waiting around for a break from the cold. These heaters can be adapted to virtually any vehicle and are reasonably priced so that you do not have to pay a fortune for the simple comfort of some heat in your seat. we prefer seat heaters to conventional heaters not only for their fast operating times but also because you do not need to have the noisy and annoying fan blowing in order to feel the heat. If you frequent cold climates, seat heaters are a must have item.
