SELF HEALING INTRODUCTION Smart Grid is sophisticated‚ digitally enhanced power systems where the use of modern communications and control technologies allows much greater robustness‚ efficiency and flexibility than today’s power systems. The American Electric Power Research Institute (EPRI)‚ an advocator of building the smart grid‚ gave this grid a definition with self-healing‚ security‚ integration‚ collaborative‚ forecast‚ optimization and interaction. While European commission define

the first generating power plant was installed in the city of Lagos in 1898. From then until 1950‚ the pattern of electricity development was in the form of individual electricity power undertaking scattered all over the towns. Some of the few undertaking were Federal Government bodies under the Public Works Department‚ some by the Native Authorities and others by the Municipal Authorities. ELECTRICITY CORPORATION OF NIGERIA (ECN). By 1950‚ in order to integrate electricity power development and make

of Substations Substations Electric power is produced at the power generating stations‚ which are generally located far away from the load centers. High voltage transmission lines are used to transmit the electric power from the generating stations to the load centers. Between the power generating station and consumers a number of transformations and switching stations are required. These are generally known as substations. Substations are important part of power system and form a link between

In an electric power system‚ a fault is any abnormal electric current. For example‚ a short circuit is a fault in which current bypasses the normal load. An open-circuit fault occurs if a circuit is interrupted by some failure. In three-phase systems‚ a fault may involve one or more phases and ground‚ or may occur only between phases. In a "ground fault" or "earth fault"‚ charge flows into the earth. The prospective short circuit current of a fault can be calculated for power systems. In power systems

having a greater potential. Hydropower therefore provides the majority of the country’s domestic power generation. Hydroelectricity is produced by three main power plants located in the north of the country: Koman (600 MW)‚ Fierze (500 MW) and Vau Dejes (250 MW). The 97 MW Vlora oil-fired power plant was commissioned in December 2009. Electricity production is almost entirely hydro-electric. In 2009 it accounted for 99.8% of production‚ with thermal (ex-oil) accounting 0.2%. (source: Enerdata)

Overview 2.1.1. Power Delivery System Con Edison delivers electricity to 3.2 million customers in New York City and Westchester County – a service territory of 660 square miles with a population of approximately 9 million people. Electricity is delivered through approximately 94‚000 miles of underground cable and almost 37‚000 miles of overhead cable. As shown in Figure 2-1‚ the Con Edison electric power delivery system is comprised of three distinct sub-systems: generation‚ transmission‚ and distribution
