摘要： PROBLEM TO BE SOLVED: To prevent a bus-bar voltage from being controlled out of a specified value, and to prevent a loading switch tap from being controlled excessively largely or extremely insufficiently.
SOLUTION: It is determined whether a tap operation is in the fourth time in a step S1, processing is progressed to determination processing in a step S2 when the determination is "N", and in this step S2, it is determined whether a voltage deviates from "voltage adjustment relay 90+dead band" by the release of a branch reactor ShR. When the determination is "Y" in the step S2, the processing is progressed to determination processing in a step S3, it is determined whether the voltage deviates from "program control-dead band" when an LR tap is lowered in this step S3, the processing is progressed to processing in a step S4 when the determination is in "N", the "lowering" of an LRT tap is performed in a step S5 by resetting the relay 90 integration, and the processing is returned to the step S1. In the determination processing in the steps S1, S3, alarm output processing is performed when the determination is "Y", and in the determination processing in the step S2, a "phase modification operation" output is performed when the determination is "N".

摘要： PROBLEM TO BE SOLVED: To allow a central device to collect detailed information on terminal devices, in a digital protective relay system.
SOLUTION: In the digital protective relay system 1, the central device 2 is connected to terminal devices 3 by a loop circuit, and the protective operation is performed by obtaining sampling data of the terminal devices 3 using the central device 2. Data obtained by multi-point sampling the detailed information on the terminal devices 3 via an interface is transmitted to multiple separation parts 3a. The data is transmitted to the central device 2 through multiplexing on an unused channel of a transmission frame format by the multiple separation parts 3a of the terminal devices 3. The detailed data of the terminal devices 3 is collected by the central device 2.
