Abstract Digital Protection & Control Of Power System 1. Introduction (Chapter 1) 1.1 The Problem The power system in general has become complex to operate in view of their increased size, both with respect to the area and capacity. To improve the reliability and the economy in operation the individual system has been interconnected.
Analog Devices μModule ® (micromodule) regulators with a PMBus I 2 C serial interface, also called PSM (power system management), enable system designers and remote operators to command and supervise a system''s power condition and consumption via a digital bus. The ability to digitally change power supply parameters reduces time-to-market and downtime by

Digital protection is based on the use of computers in power line relaying. Since the late 1960s, digital devices and techniques have been applied to almost all new protection schemes. Today the technology is moving towards standardised hardware platforms; at the software level, however, there remains a huge variety in approaches and protection algorithms.
Power system protection is defined as detecting abnormal operating conditions in a power system and preventing further threats such as instability or equipment damages, by clearing the faulted part as soon as possible . Thus, the protective equipment should be able to measure the system parameters and distinguish unusual conditions immediately.
After introductory chapters related to protection technology and functions, Digital Signal Processing in Power System Protection and Control presents the digital algorithms for signal filtering, followed by measurement algorithms of the most commonly-used protection criteria values and decision-making methods in protective relays.
The power system equipment in a substation could be protected using digital computers, and since that time, research in digital protection has attracted many investigators. Research activity has covered virtually every protection technique, and many novel algorithms and associated hardware implementations have emerged.

As the protected components of the electrical systems have changed in size, configuration and their critical roles in the power system supply, some protection aspects need to be revisited (i.e. the use of protection systems to reduce arc flash energy in distribution systems).
Most types of protective devices such as digital relays, electromechanical relays and fuses can be observed in the same industrial power system. However, in such a highly diverse environment, coordinating different types of protective devices such as relay-fuse is a challenging task when using standard approaches.
