Characteristics of Fault Detection System for Smart Grid Distribution Network

摘要

Smart Grid is the electric power network which is more reliable, more secure, more economic, environmentally friendly and safer. According to the European Regulators Group for Electricity and Gas the smart grid is an electricity network that can efficiently integrate the behavior and actions of all users connected to it -generators, consumers and those that do both - in order to ensure economically efficient, sustainable power system with low losses and high levels of quality and security of supply and safety. Smart power grid combines the traditional power supply technology, modern communication systems and information technologies extended by the new network state estimation and control algorithms. New generation power networks must be flexible and essentially eliminate the divide between the power generators, power grid operators and consumers. Generally, the smart grid is the vision of the future electric power network with high density of the distribution generation and high level of electric power supply reliability.
