Abstract
Синхронная вставка постоянного тока, содержащая на каждой стороне шин мостовые преобразователи переменно-постоянного тока, соединенные полюсами через реактор, выключатели, связывающие первичные обмотки трансформаторов с шинами, вторичные обмотки трансформаторов с разными группами соединения, а между шинами введено соединение в виде линии переменного тока, отличающаяся тем, что группы соединения трансформаторов с разных сторон электропередачи отличаются на величину, обеспечивающую в номинальном режиме противофазный сдвиг первой гармоники выпрямленного напряжения, что достигается выполнением обмоток трансформаторов, обеспечивающим разницу фазового сдвига их напряжений, равнуюΔφ=180-β-α-(γ+γ)/2=180/m - электрических градусов,где Δφ - фазовый сдвиг напряжения шин с двух сторон,α, β - углы регулирования выпрямителя и опережения инвертора,γ, γ- их углы коммутации,m - пульсность преобразователя.A DC synchronous insert containing on each side of the busbar AC-DC bridge converters connected by poles through a reactor, switches connecting the transformer primary windings to the buses, transformer secondary windings with different connection groups, and an AC line connection was introduced between the buses, characterized in that the connection groups of transformers from different sides of the power transmission differ by a value that ensures in nominal mode the antiphase shift of the first ha monics of the rectified voltage, which is achieved by performing transformer windings providing a difference in the phase shift of their voltages equal to Δφ = 180-β-α- (γ + γ) / 2 = 180 / m - electrical degrees, where Δφ is the phase shift of the bus voltage from two sides , α, β are the control angles of the rectifier and the lead of the inverter, γ, γ are their switching angles, m is the pulse frequency of the converter.
