Problems solved by technology

While these recent advances in upgrading the grid have been beneficial, more are needed
In the U.S. alone, it is reported that half of its generating capacity is unused, half of its long-distance transmission grid capacity is unused, and two-thirds of its local distribution is unused

Embodiment Construction

[0034] By way of overview, the preferred embodiments described below relate to a method and system for managing an electrical grid. As discussed in more detail below, certain aspects relate to the grid itself (including hardware and software in power transmission and / or distribution). In addition, certain aspects are related to the functional capabilities of the central management of the grid. These functional capabilities can be grouped into two categories, operations and applications. Operational services allow utilities to monitor and manage smart grid infrastructure (such as applications, networks, servers, sensors, etc.).

[0035] As discussed in more detail below, the application capabilities may relate to measurement and control of the grid itself. Specifically, application services implement functions that may be important for smart grids, and may include: (1) data collection processing; (2) data classification and persistence processing; and (3) observability proces...

Abstract

An outage intelligence application receives event messages indicative of occurrences associated with various devices within a power grid. The outage intelligence application determines a state of the various devices based on the event messages. Based on the event messages, the outage intelligence application can determine can determine and confirm an outage condition associate with a particular device. A fault intelligence application receives synchrophasor data for each phase in a multi-phase power grid. The synchrophasor includes phasor magnitude and phasor angle information for each phased. Based on the synchrophasor data, the fault intelligence application determines the presence of a fault involving one or more of the phases and identifies a particular fault type.

Description

technical field [0001] The present invention relates generally to a system and method for managing an electrical grid, and more particularly, to a system and method for managing outages and fault conditions in an electrical grid. Background technique [0002] A grid can include one or all of the following: generation, transmission, and distribution. Power plants can be used to generate electricity, such as coal-fired power plants, nuclear power plants, and the like. For efficiency purposes, the generated electricity is boosted to a very high voltage (such as 345 kilovolts) and transmitted over transmission lines. The transmission lines can transmit electricity over long distances, such as across state lines or across international borders, until it reaches a wholesale customer, which can be a company owning a local distribution network. The transmission line may terminate at a transmission substation, which may step down the very high voltage to an intermediate voltage (eg...
