Electrical utility reliability indices such as System Average Interruption Frequency Index, Duration Customer and Momentary Index are adequately defined in IEEE Std. 1366-2012, serve the purpose for which they were developed. However, explosive growth of electronics industry moving toward internet things, along with data center development necessary to support growth, has had significant impact on an aging power distribution system. As world evolves notion smart grid, several new metrics...

High reliability (and availability) with low life-cycle costs are general goals for all maintenance programs. An effective preventative (PM) regime balances the cost of elimination degradation failure mechanisms through preemptive intervention. Failures in operation require corrective (CM) and often most expensive to repair. PM is conducted reduce probability specific failures hence CM burden cost. However, actions can themselves introduce additional damage mechanisms. Determining optimum...

One of the most common questions in early stages designing a new facility is whether normal utility supply to fire pump reliable enough "tap ahead main" or so unreliable that it must have an emergency power source, typically on-site generator. Apart from obligation meet life safety objectives, not uncommon capital on order $100 000 $1 million at stake for backup source. Until now, decision has only been answered with intuition - using combination outage history and anecdotes about what...

Reliability-Centered Maintenance (RCM) is a proven technology to optimize the maintenance processes and another logical step in improving overall performance reliability of critical facility while reducing total cost ownership. This paper will introduce RCM use an automatic transfer switch standby generator back up utility power as example system demonstrate process.

PowerSecure (PS), a subsidiary of Southern Company, operates over 1600 microgrids including large fleet standby diesel generators. Machines range from 125 to 2800 kW. There are two missions: power after utility failure and load management when is available. This report updates generator reliability data published 20 years ago. These results first derived uniform records distributed acquisition system. The unique aspects this effort include automated collection, analysis, storage producing...

PowerSecure (PS), a subsidiary of Southern Company, operates over 1600 microgrids and as result manages large fleet standby diesel generators. The machines range in power from 125 to 2800 kW. Most the are used two different missions. In addition providing after utility failure, most serve one or more utility-driven load management applications, including demand response, coincident peak capacity markets, automatic frequency generation during spot market prices. MTechnology, Inc., was...

Reliability Centered Maintenance (RCM) is a proven technology to optimize the maintenance processes and another logical step in improving overall performance reliability of critical facility while reducing total cost ownership (TCO). This paper will introduce RCM use an Automatic Transfer Switch (ATS) standby generator back up utility power as example system demonstrate process.

Electrical utility reliability indices, such as SAIFI, SAIDI, CAIDI, CAIFI, and MAIFI are adequately defined in IEEE Std 1366-2012 [1] serve the purpose for which they were developed. However, explosive growth of electronics industry moving toward an "internet things," along with data center development necessary to support has had significant impact on aging power distribution system. As world evolves notion "smart grid," several new metrics needed evaluate electrical customer's side meter.

This paper describes a test facility designed and operated by MTechnology, Inc. (MTech) for development testing of grid-connected Distributed Energy Resources (DER). The is capable inverters, loads, related DER connection equipment up to 500 kVA, with an upgrade 2000 kVA in progress. includes simulation, desktop equipment, benchtop fixtures that utilize full-scale hardware at reduced voltage current, synthetic grid full power under transient fault conditions, direct the local utility...

This article presents an idea of achieving reliability through Industrial Internet Things (IIoT) for industrial power systems. It proposes hybrid approach predictive and corrective maintenance. discusses the self-corrective maintenance (SCM) paradigm as systems along with condition-based utilizing IIoT to achieve it. As it is well known that industries pay huge penalty down time, suffer meet demands years. Study witnesses its cost in millions dollars yearly production disruptions. can be...

A power plant comprising two 200 kW/230 kVA fuel cells was installed and operated over a period of 15 months. Details the operating experience economics application are discussed.

MTechnology, Inc., was retained to design and develop the power electronics system for a distributed generation plant. The plant incorporated four 250 kW DC modules. required operate both in grid-connect grid-independent modes, with constraints upon acceptable transients applied internal bus during transitions between modes. transition from mode control assume responsibility voltage regulation balance ancillary loads. Operation faced challenge of starting relatively large compressor fan...
