摘要： PROBLEM TO BE SOLVED: To reduce development cost by synchronizing the times processed by a computer for input and output processing with the times of day processed by a computer for protection relay calculation, and adopting as a scheme for data communication between the computers a transmission right scheme where data communication is performed on rotating basis. SOLUTION: When a computer 30 for input/output processing as an input/ output processing terminal for transmission line protection outputs system information to LAN 50, a computer 40 for protective relay calculation is fed with the system information from the LAN 50 and performs relay operation. If an circuit breaker in the power system needs to be opened, the computer for protective relay calculation outputs a trip signal to the LAN 50. The transmission control unit of the LAN 50 performs transmission right communication control process to perform transmission in rotation, so that the data will not collide with each other. Since the protective relay system is constituted using general- purpose computers as mentioned and the general-purpose computers are connected with each other via LAN 50, development cost can be reduced by applying innovated general-purpose technologies.

摘要： PROBLEM TO BE SOLVED: To reduce development cost by forming a device which performs inputting of system information and outputting of a trip signal using a general- purpose computer and a device which performs relay computation using a general-purpose computer, and performing the connection between general-purpose computer through LAN. SOLUTION: System information indicating the state of an electric power system are inputted into general-purpose input/output processing computers 31-35, and outputted to LAN 50, and a trip signal is inputted from the LAN 50 and outputted to a trip circuit in a breaker. The input/output terminal 31 which is an input/output processing computer for protecting a transmission line is a processing terminal for protecting the transmission line, the input/output terminals 32, 33 for protecting transformer is a processing terminal for protecting a transformer, the input/output terminal 34 for protecting a bus is a processing terminal for protecting the bus, and the input/output terminal 35 for protecting a distribution line is a processing terminal for protecting the distribution line. It is thus possible to reduce development cost.

摘要： PROBLEM TO BE SOLVED: To reduce development costs by connecting general-purpose computers together via LAN, and synchronizing the times at which processings are made by a computer for input/output processing with times processed by a computer for protection relay calculation. SOLUTION: When a computer 30 for input/output processing as an input/ output processing terminal for transmission line protection outputs system information to LAN 50, a general-purpose computer 40 for protection relay calculation is fed with the system information from the LAN 50 and performs relay operation. If an circuit breaker in the power system needs to be opened, the computer for protection relay calculation outputs a trip signal to the LAN 50. At this time, since the timing for sampling the respective amounts of information on the power system needs to be the same, a time-of-day synchronizing means is constituted, using the transfer control parts 64 and 69 of the computers, and the time-of-day synchronization control between the computers 30 and 40 is carried out by software processing.

摘要： PROBLEM TO BE SOLVED: To minimize a range of interruption and identify a failure block, by installing a failure block judging means which identifies a failure block based on the result of detection by a failure detector which is installed in each protection block defined by dividing a power system into minimum interruption blocks, and isolating a failure block identified by the failure block judging means from the power system. SOLUTION: A line protection block 51 contains failure detectors 41, 22, 49, and protects a transmission line 5, and a line protection block 52 contains failure detectors 43, 44, and protects a transmission line 6. Further, a line protection block 53 contains failure detectors 45, 46, 50, and protects a transmission line 7, and a line protection block 54 contains failure detectors 47, 48, and protects a transmission line 8. The results from the failure detectors 41-50 at terminals, collected for each line protection block are judged by a failure block judging means corresponding to the line protection blocks to detect a failure block. Then the failure block is isolated from the power system by an isolation command outputting means.

摘要： PROBLEM TO BE SOLVED: To detect only the specified components of system high frequency, and remove other components completely, and flatten the inclination of amplitude-frequency property, by setting the fundamental transmission function of a digital filter so that it can be expressed in a specified formula. SOLUTION: The fundamental transmission function H6(Z) of a digital filter is set so that it can be expressed in a formula, where, (h) is sampling frequency/ inputted reference frequency, and (p) is a designated factor. Hereby, the degree of the digital filter becomes low degree, so this filter can detect only the specified high frequency components at high speed, and can remove other components completely. Moreover, this can flatten the inclination of amplitude-frequency property, by adding the specified factor (p) to the fundamental transmission function H6(Z).
