China's UHVDC industrialized overseas market or greater increment

1. in the rapid development of domestic special / ultra high voltage direct current (UHV), strong competitiveness has been formed.
From the start of Ge Nan DC, China's DC industry has formed the largest DC transmission system in the world after decades of mode and development. In the rapid development, it has also cultivated a strong competitive industry company. At present, not only has realized the localization of EHV DC, but also has developed UHVDC independently and realized industrialization. At present, China has strong competitiveness in the field of HVDC.
2. the excellent domestic enterprises have the strength to compete with the international giants.
In recent years, China has successfully implemented the Brazil beautiful landscape electricity delivery project, of which two mainly by Chinese enterprises EPC and provide equipment. In 2017, China's EPC Pakistan DC started, Turkey's back-to-back DC and the UK set up the project of the Durham straight line. All the domestic projects were successful in the competition with SIEMENS and ABB.
3. DC / SOFC can benefit from global industrialization.
The economy of EHV / UHV DC in the world have been recognized, at present, China has eight pay eight straight UHV project is completed and put into operation, the "two pay three straight under construction period, this year added a UHV approved (approval is expected by the end of the domestic as well as DC project). However, across the globe, intercontinental transmission projects, such as intercontinental transmission, may be gradually expanded. A total of UHV transmission line has more than 32 thousand kilometers, the converter capacity reached 3.3 million KVA (kw), significantly higher than the global average. In recent years, the domestic electric power equipment successfully in Brazil sent a beautiful mountain hydropower project, which is mainly composed of two Chinese enterprises EPC and provide equipment; in 2017, Chinese enterprise has won the Pakistan HVDC project in Turkey, where the city of back-to-back DC project, British Shetland HVDC project. In the follow-up, the East African DC and Egypt DC are expected to start gradually. In the future, most of the global hydropower transmission and long distance large capacity transmission will use ultra / ultra high voltage direct current transmission technology, and China's DC industry will have long-term output capability.
4. the flexible DC is expected to relay UHV DC:
Flexible DC has a series of excellent technical properties, and is especially suitable for wind farm access. Now it is limited by high cost, limited transmission capacity (insufficient power of semiconductor power devices), and is still in the early stage of commercial application. At present, the 3 terminal, 5 terminal and other multi terminal flexible DC test projects have been successfully completed in the State Grid and China Southern Power Grid, and a flexible DC project with a + 400kV has been tested. It is estimated that the + 500kV flexible DC project will soon be put into operation, and the flexible DC will start to commercialize rapidly.
5. Asia, Africa and other developing countries have continued to have new markets for electricity consumption.
Compared with the developed countries, including China, many of the Afro Asian region development Chinese family home machine, electricity consumption per capita is at a low level, especially in Southeast Asia, South Asia, the population in this area is close to 2 billion, in addition to Singapore, Brunei, per capita in basic 2kkwh/ people with power, the power industry from construction investment the illusion of consumption has great potential.
6. domestic equipment manufacturing enterprises have comparative advantages
China's electric power system has long formed a system of division of labor, protection, automation, power control and other products and service level is in the leading position, enterprises have strong overall strength, compared with international giants, system customization ability and more cost-effective, equipment capacity with output power.
7. China's equipment enterprises are transforming from equipment suppliers to solutions
The increment of the overseas market is an important source of the growth of the high voltage equipment enterprises. Because of the traditional equipment manufacturing capacity and domestic demand has been a certain mismatch, and enterprise assets often heavier, the domestic high-speed development in the past decades, providing infrastructure support power especially in high voltage power equipment enterprise, and has withstood the domestic high load and complicated environment test, if the output of manufacturing with the general ability of the enterprise can continue to achieve overseas market, electric power equipment enterprise still has space of continuous development.
