摘要： PROBLEM TO BE SOLVED: To solve a phase angle stability problem and a voltage problem since a bus voltage of a substation over-rises due to a fluctuation of a phase angle inside a generator by a disturbance of the generator and a large fluctuation of a power line stream if power limit control is performed when a system breaks down although a large amount of power capacitors are used for maintaining a bus voltage of the substation at stationary time in the power system transmitting a power from a large capacity power supply at a remote place. SOLUTION: A system stabilizing device is provided with database storing data obtained by previously calculating a power control amount at the power station at an assumed accident and a phase modification control amount at the substation operating/interrupting a phase modification facility by using an electric circuit model of the electric system and online data. The device is provided with a restoration/confirmation means for a reduction gradient of phase angle fluctuation of the generator and a substation bus voltage at the system accident by a previous operation. When fault information of the system is received, phase modification control is performed based on the substation phase modulation control amount corresponding to the fault which is read from the database and data on its execution timing.

摘要： PROBLEM TO BE SOLVED: To obtain a power system stabilizing apparatus capable of stabilizing both frequencies and voltages of a separate system, and to provide a method of controlling the same.
SOLUTION: At a control execution unit 29, two-staged control, i.e., first-stage control and second-stage control, is sequentially carried out. A second-stage control selection unit 24 selects either disconnection of generators 1a to 1c or loads 5a to 5c or disconnection or connection of phase modifying devices 6a to 6c as control operation in the second-stage control based on the following combination: a combination of the plus or minus of a frequency variation and the plus or minus of a voltage variation obtained when a certain time has passed after the execution of the first-stage control. Each operation amount in the second-stage control is computed by a correction effective power control computation unit 25, a correction reactive power control computation unit 26, an emergency effective power control computation unit 27, and an emergency reactive power control computation unit 28.

摘要： PROBLEM TO BE SOLVED: To provide a system stabilization system in which high speediness which is a strong point of a pre-calculation method and flexibility which is a strong point of a post-calculation method are effectively combined. SOLUTION: The system stabilization system stabilizes a power system by controlling a power generator in conformity with the situation of an accident when an accident occurs in the power system. When the accident occurs in the power system, main control is performed based on the control table obtained by performing pre-simulation related to the pre-assumed accident case using the pre-calculation method, and correction control is performed by using the post-calculation method after execution of the main control based on the result obtained by measuring an actual system phenomenon after occurrence of the accident when the control amount is short in the main control.
