Abstract
The invention discloses a novel design model of an alternating current filter for an ultra-high voltage direct current power transmission system. The method is to meet engineering need by designing the novel model of the alternating current filter BP11/BP13 on the premise of satisfying the harmonic performance of an alternating current bus. The alternating current filter is a double-tuned filter formed by adopting a proposal of parallelly connecting two single-tuned filters (BP11 and BP13), and avoids problems of heavy current and big noise which are difficult to solve in a low-voltage reactor of the prior double-tuned filter BP11/13.
Description
Technical field
The present invention relates to the complete designing technique of extra-high voltage DC transmission system, emphasis by theoretical analysis and calculation, modeling assessment, alternating current filter design relatively, study the economy and the feasibility of different filter schemes, thereby determined a kind of new alternating current filter pattern.
Background technology
China's electrical network is being faced with unprecedented development situation along with the high speed development of national economy and power industry.Characteristics such as the electrical distance of sending is far away because direct current transportation has, power transmission capacity is big, control is flexible, in following one, 20 year, high pressure and even extra-high voltage direct-current transmission will play crucial effect to the development of China's electrical network aspect the remote large capacity transmission and on national network two.
The converter of high voltage direct current transmission is a highly nonlinear harmonic source, can produce abundant harmonic wave during the HVDC (High Voltage Direct Current) transmission system operation in AC system.The harmonic wave that injects AC network can cause the harmonic pollution of electrical network, reduces the economic benefit of electrical network, the safety of equipment such as harm generator.General all AC side by current conversion station install dissimilar filters additional and reach the purpose that absorbs harmonic wave.
