Description

ABB GDC806A0101 3BHE028761R0101 Processor module

Because the insulated gate bipolar transistor (IGBT) has the advantages of small driving power and simple driving circuit, fast switching speed and small loss, low saturation voltage, high voltage resistance, large current and so on, in the flexible DC

It has been widely used in power grid. The existing MMC converter valves are designed with IGBT switching devices. In fact, IGBT was born in the early 1980s and acquired in the 1990s

Rapid development. However, the traditional welded IGBTs have a small capacity, low reliability, and open circuit characteristics after failure, so the early IGBTs were mainly used in the middle and low pressure field until the birth of the crimp IGBTs

It has been used in high voltage and high power power electronic converter. The capacity of IGBT devices has been gradually increased from the earliest 600V/6A class to the 4.5kV/3kA level to date.

IGCT was born in 1996, because its core GCT chip is improved from the thyristor, so naturally has the characteristics of large capacity and reliability of thyristor. IGCT devices have been there since 2000

4.5kV/4kA level, compared to the voltage IGBT until 2012 to achieve the same power rating, with; Inch IGCT devices will be used in the future, and IGCT will remain in capacity for IGBT

Hold a big advantage.

In addition, although IGBT has outstanding advantages, compared with current-type devices, it still has many problems such as large on-state voltage drop, low reliability and high manufacturing cost, so it has a lot of room for improvement. Especially in offshore wind power

In flexible HVDC transmission system, the number of switching devices used is very large. If the characteristics of IGBT devices can be improved, the efficiency and reliability can be further improved, and the cost can be reduced, it will have great attraction

Force and application prospect.

2. Solutions

The multilevel modulation of modular multilevel converters (MMCS) greatly reduces the switching frequency of power devices, which brings an opportunity for the application of integrated [] pole commutator thyristor (IGCT). Compared to IGBT, IGCT

The on-state voltage drop and cost can be reduced to more than 1/3, and IGCT has a very strong surge current, short circuit failure and explosion-proof ability, without adding auxiliary circuit can realize redundancy and explosion-proof, to ensure flexibility

High reliability requirements for maintenance-free direct transmission systems. This technology has great significance and broad application prospect to realize flexible HVDC system with higher voltage, higher power, higher efficiency and higher reliability.

With the development and application of wind power generation technology, the development of onshore wind power has tended to saturation, while the offshore wind power has not been fully utilized, which has a huge potential for development. Offshore wind resources are abundant. Yes

With fewer negative impacts on the environment, more stable wind speed, large power generation, wide space, allowing more large-scale fan units, offshore wind power will be the inevitable trend of wind power development in the future. As renewable energy

The important components of source are getting more and more attention. Europe is by far the largest region for offshore wind capacity. According to the European Wind Energy Association's target, wind energy will provide 15.7% of Europe's electricity by 2020

By 2030, it will be 28.5 percent. Among them, the installed capacity of European offshore wind power will reach about 40GW in 2020, accounting for about 18% of the total installed capacity of European wind power; In 2030

Europe's offshore wind capacity will reach about 150GW, accounting for about 37.5 per cent of Europe's total installed wind capacity. China's offshore wind power is also developing rapidly. By the end of 2016, the installed capacity of China's completed offshore wind power projects totaled 1.627GW, ranking third in the world in 2016. According to the "13th Five-Year Plan" for wind power development, China's offshore wind power grid-connected capacity is planned to reach 5GW by the end of 2020

Above.

In view of the current development trend of offshore wind power technology, in order to obtain more wind power, the installation of a single project of offshore wind power platform is increasing, and the offshore distance is also developing from near to far. European sea

In 2016, the average offshore distance of new projects reached 43.5km, and the longest offshore distance reached 115km. The transmission and grid connection of electricity has been the bottleneck of wind power development, and the capacity of offshore wind farms is increasing

Under the trend of larger and farther offshore distance, flexible DC transmission technology based on IGBT and IGCT converter valve becomes an inevitable choice. The problem of offshore wind power transmission and grid connection is more prominent, which is our country sea

The development of wind power provides a strong guarantee for power transmission and grid connection.

In addition to offshore wind power, the technology can also be applied to onshore new energy pooling, AC system interconnection and DC power grids.
