Uses of Computer and Microprocessor

Uses of Computer and Microprocessor: Uses of Computer and Microprocessor – The first methods for solving various power system problems were AC and DC network analyzers developed in early 1930s. AC analyzers were used for load flow and stability studies whereas DC were preferred for short-circuit studies. Analogue computers were developed in 1940s and the …

Deregulation Meaning

Deregulation Meaning: For over one hundred years, the electric power industry worldwide operated as a regulated industry. In any area there was only one company or government agency (mostly state-owned) that produced, transmitted, distributed and sold electric power and services. Deregulation Meaning concept came in early 1990s. It brought in changes designed to encourage competition. …
