摘要： A State and Topology Processor (STP) may be communicatively coupled to one or more intelligent electronic devices (IEDs) communicatively coupled to a electrical power system to obtain one or more current measurements, voltage measurements, and dynamic topology data therefrom. The STP may receive the measurement data and may determine a current topology and a voltage topology therefrom. A current processor may use the current topology and the current measurements to refine the measurements, perform KCL, unbalance, symmetrical component, and consistency checks on the electrical power system. The voltage processor may use the voltage topology and the voltage measurements to perform similar checks on the electrical power system. One or more alarms may be generated responsive to the checks. The data may be displayed to a user in a display of a human machine interface and/or may be transmitted to a user programmable task module, and/or an external control unit.

摘要： A notification device and method associated therewith for notifying an electric power consumer to reduce electric power consumption when the notification device detects selected power system conditions. The notification device detects conditions on the electric power system that would likely be alleviated by a reduction in consumer power consumption and provides a visual and/or audible notification to the consumer accordingly. The condition may be indicative of strains on the electric power system and/or higher cost of electricity distributed to the consumer. The condition may be induced by the electric power utility. The notification device and method disclosed herein allow the consumer to decide whether to reduce power consumption as is practical for the consumer.

摘要： A system and method for monitoring the rotation of a generator rotor and calculating a power angle using an optical rotor displacement monitor. The monitor uses a light beam directed toward the rotor to detect a marking thereon, and generates an electrical pulse when the marking is detected. The time between the pulse and a reference point (such as a zero crossing) of the signal waveform from the terminals of the generator is used to calculate the power angle of the generator. The system is adaptive in that it can account for new markings on the rotor. The system may be connected to a network so that power angles from various generators on the electrical network may be compared. The system may further be connected to a common time source such that a time stamp may be applied to the power angles from various generators, allowing for more accurate comparison of the power angles.

摘要： The system tests front panel lights, such as LEDs, on an electronic instrument, the front panel lights being normally used to indicate the status of selected output conditions of the instrument. The system also uses the LEDs to communicate additional information concerning the instrument, in particular the operation of the clock system for the instrument. The system includes a plurality of timers, each timer being associated with one front panel LED. The user sets the timers a specific amount of time (e.g. one second) apart, with each LED being programmed with a different timer. The LEDs light in succession in response to the clock reaching a preselected time. If one or more of the LEDs do not light, failure of the LEDs is indicated. If the LEDs do not light in proper order or at the expected time, investigation of the clock system is indicated.

摘要： The relay includes an input module capable of receiving 70 volt and 5 amp signals, respectively, from conventional instrument transformers, which are responsive to power line signals at their primaries. Output signals from the input module have specified, standardized levels suitable for electronic processing circuits, i.e. 1.4 volts and 0.1 volt. The output signals from the input module are applied through an accessible connector to a separate processing module which uses those signals in a conventional manner to determine possible faults on the power line. Low-level testing is accomplished by testing the outputs of the input module and by applying test signals simulating the standardized outputs of the input module to the processing module.

摘要： The system includes a blocking counter which is set to 255 quarter cycles and the output contacts of the protective relay are blocked for five quarter cycles if the first order difference between two successive quarter-cycle samples of current is above a selected threshold, referred to as the last previous and the first samples. The first order difference between the first and the next successive (second) samples is compared against a second threshold and the instantaneous value of the current sample is compared against the second threshold. If both comparisons are above the second threshold, then the output contacts are unblocked. If not, such that a constant DC A/D converter output or an A/D spike is indicated, then the outputs remain blocked for the full five quarter cycles, which is sufficient time to permit the A/D spike to disappear and to recognize a constant DC output from the A/D converter.
