IEEE Recommended Practice for the Design of Reliable Industrial and Commercial Power Systems

Buy
The design of reliable industrial and commercial power systems is of considerable interest to many people. Prior to 1962, a qualitative viewpoint was taken when attempting to achieve this objective. The need for a quantitative approach was first recognized in the early 1960s when a small group of pioneers led by W. H. Dickinson organized an extensive AIEE survey of the reliability of electrical equipment in industrial plants. The AIEE survey that was taken in 1962 was followed by several IEEE reliability surveys, which were published in 1973 through 1979. These surveys from the the 1970s were the basis for the reliability data contained in IEEE Std 493-1980. Six additional IEEE reliability surveys have been conducted and published during the 1980s and have been updated in this revision of IEEE Std 493-1997. The 1990 edition included pertinent tutorial reliability material and the cost of power interruptions data.

IEEE Std 493-1997 presents two new chapters, Chapter 9, a new methodology for estimating the frequency of voltage sags at industrial and commercial sites, and Chapter 10, a methodology for estimating the number of tests required to demonstrate reliability of emergency and standby systems. New appendixes have been added on high- and low-voltage circuit breaker reliability data, guarantees of gas turbines and combined cycle generating units, transmission line and equipment outage data, interruption costs, and expectations for service reliability. The existing appendices have been updated.

FPGAs: Instant Access
Various aspects of PLDs, ASICs, and FPGAs will be discussed later in more detail. For now, we need only be aware that PLDs are devices whose i nternal architecture is predetermined by the manufacturer, but are created in such a way that they can be configured by engineers in the field to perform a variety of different functions. In comparison to an...
