摘要： A series compensation generator SCG is installed in a transmission line that links various substations SS and the transmission capability of the system as a whole can be increased by regulating the equivalent reactance of the transmission line. Series compensation generator SCG generates a voltage of which the phase angle is shifted substantially 90° in relation to the current flowing in the transmission line, and it also generates a voltage that compensates the voltage drop due to the equivalent reactance. Also, when an electrical fluctuation phenomenon (power oscillation) occurs in the transmission line, it is possible speedily to suppress the power oscillation by detecting the power fluctuation of the transmission line and controlling the compensating voltage of series compensation generator SCG so that it suppresses that power fluctuation.

摘要： The controller for a power converter of the present invention:calculates the range number in which the voltage command vector for a multi-level converter is present;rotates the voltage command vector through a specified angle;performs coordinate transformation of that vector to a vector in an oblique coordinate system which takes the vector in the a axis direction and a vector which has been rotated through a specified angle anti-clockwise from the a axis as two unit vectors;splits the converter output-enabled portion of the vector diagram of the -30 degrees +30 degrees range of the spatial vector diagram in which output vector is positioned, which has undergone oblique coordinate transformation, into square-shape patterns so that the outputs vector is positioned in the upper left/the lower right/both the lower left and upper right of each square-shape pattern;splits any square-shape pattern which holds the output vector in both its lower left and its upper right into two triangular domains by a segment which joins the upper left vertex and the lower right vertex;judges in which square-shape pattern/triangular domain in the domain-split oblique coordinate system diagram the voltage command vector which has undergone oblique coordinate transformation is present; andselects, rotates through a specified angle and calculates the output vector which corresponds to that domain.
