Abstract: Embodiments of the disclosure relate to analyzing costs, and more particularly, to analyzing costs associated with a power plant asset. In one embodiment, a system can include a first sensor and a first computer communicatively coupled to the first sensor. The first computer can be configured to automatically obtain via the first sensor, a first set of performance parameters of the first power plant asset over a period of time. The first computer can be further configured to compute from the first set of performance parameters, a first cost factor that is defined, at least in part, on the basis of an amount of electric power generated by the first power plant asset over the period of time.

Abstract: An automatic circuit recloser is automatically removed from service prior to battery failure. Logic implemented on the automatic circuit recloser is used to determine whether a battery of the automatic circuit recloser may power operation of the automatic circuit recloser in place of a primary power source of the automatic circuit recloser is determined. The logic is also used to signal for the automatic circuit recloser to be automatically tripped when the battery may not power operation of the automatic circuit recloser in place of the primary power source. The logic also may be used to determine whether the battery is of a marginal quality in which the capability of the battery to power operation of the automatic circuit recloser is compromised, and to issue an alarm to indicate that the battery is of the marginal quality.

Abstract: Automatically de-energizing and re-energizing a section of a distribution feeder circuit includes detecting, using a module of a protective device, whether a section of a distribution feeder circuit upstream of the protective device has been de-energized and whether the protective device may be opened automatically. The module signals for the protective device to be opened when the section has been de-energized and when the protective device may be opened automatically. The module also is used to detect whether the protective device has been opened and may be closed automatically, and whether the section of the distribution feeder circuit upstream of the protective device has stabilized. The module is used to signal for the protective device to be closed automatically when the protective device has been opened automatically and may be closed automatically, and when the section of the distribution feeder circuit upstream of the protective device has stabilized.
