Hvdc converter transformer

HVDC transformers are either built as single-phase or three phase units as per our requirement. Insultion provided for Converter transformer is very high as it needs to withstand voltage stress under both AC and DC condition. We may make mistakes spelling, program bug, typing mistake and etc. We highly respect your findings. The ones who are crazy enough to think they can change the world are the ones who do. Report Us We may make mistakes spelling, program bug, typing mistake and etc.

Error Line Corrected Line Send. Operators can optimze operations based on customized data analytics and minimize outage times. HVDC transformers are used as coupling elements between AC grids and high-power rectifiers to carry power onshore or bridge long distances. Back-to-back links are an easy solution for connecting two AC networks with deviating frequencies.

Grid operators strengthen and optimize the performance of their grids with back-to-back links. Besides, back-to-back links allow networ users to balance varying loads and generation caused by different time zones or usage patterns. Our engineers excel in replacing HVDC transformer originals, producing units that replicate performance, capacities and dimensions of the original unit, but offer the latest in transformer innovation. HVDC transformers are subject to operating conditions that set them apart from conventional system or power transformers.

These conditions include:. Two or three high or ultra-high voltage windings but no low voltage winding inside of the transformer. The high harmonics content of the operating current results from the virtually quadratic current blocks of the power converter.

The odd-numbered harmonics with the ordinal numbers of 5, 7, 11, 13, 17 cause additional losses in the windings and other structural parts. The high bulk power ratings also require a high rating of HVDC classic converter transformers which must share specific performance parameters, e. It usually meets grid code requirements. Condenser-graded bushings for all applications for rated voltages from 24 kV to 1, kV.

Reliable and highly efficient power transformation for different application areas: power generation, power transmission, industry, infrastructure. Tailored to customer needs. Siemens High Voltage Direct Current systems HVDC provide the most efficient way of energy transmission over long distances and to support the improvement of the grid stability. An HVDC system with low losses consist of e.

Yet, these contributions to more carbon-neutral energy take place in remote areas often hundreds or even thousands of kilometers away from the centers of consumption. Effective solutions are vital to connecting all distributed power generation sources to the grid to make electricity available where it is really needed. High-voltage direct-current HVDC converter transformers. Transformers Magazine, October Where transmission power capability of HVDC systems is steadily increasing, our customers can rely on our experienced design teams to help master transmission and grid challenges around the globe.

HVDC makes a difference - attention to every detail. Reliability lowers total cost of ownership. Factory network. Covering the HVDC transformer market with leading competence. Increase transformer reliability. Sensproducts Website. As coupling elements between AC grids and high-power rectifiers, they adapt the voltage, insulate the rectifier itself from the AC grid and generate the necessary phase shift.

HVDC transformers of Siemens Energy meet all requirements for power, voltage, mode of operation, low-noise, connection types, types of cooling, transport, and installation. They also comply with specific national design requirements. These conditions include: Combined voltage stresses with both AC and DC Two or three high or ultra-high voltage windings but no low voltage winding inside of the transformer High harmonics content of the operating current DC pre-magnetization of the core Very narrow tolerances in between units, especially in terms of impedance voltage.
