Siemens High Voltage DC Converter Transformer
Converter Transformer (Converter Transformer) The power transformer connected between the converter bridge and the AC system. The converter transformer is used to realize the connection between the converter bridge and the AC bus, and to provide a three-phase commutation voltage for the converter bridge whose neutral point is not grounded. The converter transformer and converter bridge are the main body that constitutes the converter unit. The HVDC converter transformer is a crucial key device in the UHV DC transmission project, and it is the core device of the converter and inverter interfaces in the AC and DC transmission systems. Its investment and safe operation are the key and important guarantee for the project to obtain power generation benefits. The key role of the converter transformer requires high reliability and high technical performance. Because of the combined effect of AC and DC electric fields and magnetic fields, the structure of the converter transformer is special and complex, the key technology is difficult, and the manufacturing environment and processing quality are strict. Carrying out research on key technologies for design and manufacture of converter transformers, conquering and transforming manufacturing conditions, and continuously improving test methods will help to fully master the design and manufacturing technology of converter transformers, realize the localization of converter transformers, and fill the domestic gap. At the same time, it can promote the further improvement and development of the design and manufacture of domestic AC and DC transmission equipment, lay the foundation for the development of UHV AC and DC transmission and transformation equipment, make good preparations, and realize the localization of converter transformers.
The role of converter transformer in DC transmission system:
1. Transmit power;
2. Transform the AC system voltage to the commutation voltage required by the converter;
3. Using the different connection methods of the transformer windings, provide two sets of two converters connected in series with two sets of three-phase symmetrical commutation voltages of equal amplitude and phase difference of 30° (fundamental electrical angle) to achieve twelve-pulse commutation flow;
4. Insulate and isolate the DC part from the AC system to avoid direct short circuit caused by the neutral point grounding of the AC system and the neutral point grounding of the DC part, making commutation impossible;
5. The leakage reactance of the converter transformer can limit the fault current;
6. It can buffer and suppress the lightning surge overvoltage wave intruding into the converter station along the AC line.
