Problems solved by technology

The suspended valve tower adopts a flexible connection method as a whole, which is mainly connected by the suspension insulator and the rotary hinge. The degree of freedom in the horizontal direction, so the overall operating stability and shock resistance of the valve tower are reduced
When the vertical structure converter valve tower is applied in high-power high-voltage DC transmission, the overall components of the valve tower need to be greatly increased, but the structure is limited, and there are many design difficulties. At the s

The converter valve tower is compact in structure, good in electrical performance and mechanical performance, and good in running stability.

Description

[0001] Technical field [0002] The present invention involves the field of power electronics technology, especially a flexible DC transmission streaming valve tower based on voltage source variables. Background technique [0003] With the growth of the economy and the continuous improvement of people's living standards, my country's demand for electricity is getting higher and higher, and my country's energy and power reserves are unevenly distributed. Therefore, how to efficiently solve the problem of electricity resources is a major Hot spots and difficulty.At present, the most commonly used is AC transmission technology, but due to the resistance loss of the wires and the loss of the AC anti -resistance, when the line is too long, all the electrical energy transmitted will be consumed on the transmission line. Therefore, Vigorous research and development of DC transmission technology have become necessary. [0004] DC transmission technology is commonly used in the stream tub...
