Abstract:
A processing arrangement for the fault situation of a local electric power transmission grid comprises a generator-specific element arranged to monitor the fault situation of a data communication bus and the statuses of the switches of the electric power transmission network and to compare the status data concerning the same switch. In case of a fault situation the generators change into droop control only if there are no other possibilities to continue with the normal adjustment of the generator.
Abstract:
Methods are provided for assessing reliability of a power system of a utility company At least one main overview display is obtained Violation markers are displayed on the one main overview display A monitored elements tab is updated with a list of monitored elements
Abstract:
Methods are provided for managing high or low voltage conditions from selected areas of a power system of a utility company. Rubber-banding or lassoing is used to select geographic areas. Potential low or high voltage situations are identified in the selected geographic areas. Geographic displays are overlayed with superimposed VAR reserves to create overlayed geographic displays for the selected geographic areas. The overlayed geographic displays are used to identify potential low or high voltage instances in the selected geographic areas.
Abstract:
A method for communicating information bundled in digital message packets via a digital network communication system is provided. The digital network communication system a sample source and each packet includes a header and a communication payload area. The method includes sampling the source at a first sample rate, selecting at least one decimation of the samples based on at least one of a plurality of algorithmic data rates and a channel bandwidth, determining a packet rate based on a plurality of algorithmic latency requirements, and transmitting the digital message packet containing decimated data on the digital network.
Abstract:
A method for operating a power distribution system is provided (figure1). The power distribution system (10) includes a plurality of components, and at least one node electronics unit (20) coupled to at least one control processing unit (24). The method includes associating a unique identifier with at least one component class of the power distribution system (10), identifying each component based on the identifier, determining a specification associated with each identifier, and operating at least one of the node electronics unit (20) and the control processing unit (24) based on the determined specification.
Abstract:
A protection system for a power distribution system is provided (figure 1). The protection system includes a central computer (28), a plurality of data modules (30), and a data network (32). The data modules (30) are each in communication with a different circuit breaker (14) of the power distribution system. The data network (32) communicates between the central computer (28) and the plurality of data modules (30). The central computer (28) sends an instruction to the plurality of data modules (30) over the data network (32) to aid in synchronization of sampling of a power condition at the plurality of data modules (30).
Abstract:
Die Erfindung betrifft ein Energieversorgungssystem, ein Einrichtungsverfahren zu dessen Einrichtung und ein Energieversorgungsverfahren. Das Energieversorgungssystem weist einen ersten Verbraucher (11) und einen zweiten Verbraucher (12), einen Netzanschluss (2), über den der erste Verbraucher (11) und der zweite Verbraucher (12) mit einem Energieversorgungsnetz verbunden sind, eine Notstromeinheit (3), welche mit dem ersten Verbraucher (11) und dem zweiten Verbraucher (12) verbunden und ausgebildet ist, bei einem am Netzanschluss (2) auftretenden Leistungsabfall des Energieversorgungsnetzes den ersten Verbraucher (11) und den zweiten Verbraucher (12) mit elektrischer Leistung zu versorgen, und einen zwischen dem zweiten Verbraucher (12) und der Notstromeinheit (3) angeordneten Trennelement (4) auf. Das Trennelement (4) ist ausgebildet, bei seiner Aktivierung eine Leistungsaufnahme aus der Notstromeinheit (3) durch den zweiten Verbraucher (12) zu unterbrechen, während der erste Verbraucher (11) weiterhin mittels der Notstromeinheit (3) mit elektrischer Leistung versorgt wird.
Abstract:
A first aspect of the invention concerns a method for charging an electrical energy store on an electric vehicle at a socket providing a power supply, particularly a single-phase 230 V or 120 V domestic socket. According to the claimed method, the charging current used to charge the electrical energy store after failure and subsequent restoration of the power supply is automatically reduced over the charging current prior to failure of the power supply.
