The present invention relates to a method of generating fault indication in a feeder remote terminal unit for a power distribution automation system. The method is performed in a distribution system that includes a plurality of feeder remote terminal units, which are installed in respective sections of a line and are configured to measure voltage, current and a phase difference of the line, and a central control unit for determining whether a fault occurs and controlling operation of the feeder remote terminal units. In the method, phases are measured by each of the feeder remote terminal units. The phase of a zero-sequence current is compared with that of a zero-sequence voltage. A direction of a fault current is calculated, and fault indication information is generated in the calculated direction of the fault current.

Disclosed is a fault diagnosis device for diagnosing a fault in a bay Intelligent Electronic Device (IED) for a substation automation system, which includes an online IED diagnosis device and a backup IED. The online IED diagnosis device includes an IED selection unit, an IED switch unit, a fault diagnosis, and a result display unit. With reference to a Substation Configuration Description (SCD) file, the online IED diagnosis device designates an IED to be tested, and extracts backup information for the IED to be tested. A backup IED replaces the operation of the IED to be tested based on the extracted backup information. Further, the online IED diagnosis device determines the occurrence or non-occurrence of a fault in the IED to be tested by analyzing response information received in response to transmission of a test pattern to the IED to be tested.

A cooling plate in which flow channels are modified to reduce temperature differences between portions of the cooling plate and provide for more uniform heat distribution within a heat generator. The flow channels of the cooling plate are formed such that a central portion of the flow channels has a greater volume than the end portions near an inlet and an outlet so that the amount of cooling water that is contained in the central portion at any one time is larger than either of the end portions near the inlet and the outlet. Likelihood of thermal deformation of the cooling plate due to thermal stress is decreased, and stability of performance of the fuel cell is increased.
