摘要： PROBLEM TO BE SOLVED: To provide a digital protective relay capable of attaining complete non- operation in exciting inrush current and positive operation in case of a system accident. SOLUTION: This digital protective relay consists of a protective element and an inrush current countermeasure element. The inrush current countermeasure element comprises a second harmonic determination computing means which outputs a second harmonic determination signal, when the rate of the second harmonic component for a first harmonic component included in AC current satisfies a prescribed condition, an overcurrent determination computing means which outputs a current determination signal when the AC voltage satisfies the prescribed condition, and an undervoltage determination computing means which outputs a voltage determination signal when the AC voltage satisfies the prescribed condition. If an accident occurs in a protective section and the second harmonic determination signal, the current determination signal, and the voltage determination signal satisfy a prescribed condition, an output permit signal is outputted to an output control part. Under the condition where the inrush current is flowing, the current determination signal and the voltage determination signal permit the output of the second harmonic determination signal so as to output an output inhibiting signal to the output control part.

摘要： PROBLEM TO BE SOLVED: To prohibit erroneous outputting of a trip signal by detecting data failure, even if a failure occurs with a memory circuit. SOLUTION: The protective relay comprises an input converter, to which a system electric quantity is introduced, a filter which introduces the output of the input converter, a conversion circuit which samples the output of the filter by a prescribed time interval and converts it into digital data, and a digital calculation part which performs protection relay calculation with the digital data. It also comprises duplexed first memory circuit and second memory circuit which allow reading/writing of the calculated data and deciding result, a memory selection circuit which separately reads each of the memory circuits, and a monitor means which determines the presence of abnormalities in memory data by comparing the data which are read, and outputs a trip signal, only when a digital relay is normal.

摘要： PROBLEM TO BE SOLVED: To solve the problem that there are limits in shortening total work time in implementing change of field work and a database, as a field worker and a person in charge of control communicate by portable terminals and mutually judge a system state and a field work state, and therefore, the implementation of a continuous work is confirmed by the portable terminal. SOLUTION: A monitoring control system has a monitoring control device to monitor and control facilities or the equipment, a remote server connected with the monitoring control device, and portable terminals equipped with monitors connected to the remote server via signal transmission line. A request for the implementation of work is transmitted from the portable terminal to the remote server via a network, and the remote server transmits an instruction for work implementation after the reception and processing of the request for work implementation. The monitoring control device decides possibility of work implementation. If the implementation of the work is possible, the name of the work plan is implemented and the implementation procedure is transmitted to the portable terminal via the remote server and the network. It is characterized in that the portable terminal displays the implementation procedure and the state of the system, or the like on the monitor. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a speed governing controller that eliminates a mechanical part and that controls a guide vane operating device that can shorten a period required for maintenance and adjustment with low cost. SOLUTION: A feedback control of a main distributing valve is performed by simulating operating characteristics using a software without taking in an actual opening of the main distributing valve. Also, an anomaly is detected using a correlation between the simulated opening of the main distributing valve and the opening of the guide vane. Accordingly, it becomes possible to eliminate a hardware to measure an actual opening of the main distributing valve and improve reliability. COPYRIGHT: (C)2003,JPO
