ELECTRICAL POWER GENERATION SYSTEM - Assignment Example There are interconnections undersea through to the Republic of Ireland (EirGrid), Isle of Man (Isle of Man to England Interconnector), Northern Ireland (HVDC Moyle), the Netherlands (BritNed), and northern France (HVDC Cross-Channel). The paper will start with the different types of grid interfaces, protection issues and short circuit change levels. Then the paper will discuss the electrical power design of the components involved in generation of the electricity. In most cases, the low scale generators are indirectly connected to the grid. The characteristics of operation and the technology of generation need the incorporation of some interfaces in between the grid of distribution and the generator. For instance, photovoltaic panel of solar produce direct current electricity and thus, converter based on the power electronics is needed in between the generator and the grid. In technologies like induction generator using wind or hydro, this generator is directly connected to the Alternating Current grid. In the interconnection of the distributed generation, protection is essential. Distribution network is configured in the radial form. In this radial form, the network has over current schemes of time graded protection. The connection of the Distribution Grid may change the present schemes of protection coordination. In case, this is ignored, the protection system may fail to work. The major issues with relation to the Distribution Grid interconnection are as follows: This is the major measure useful in coordinating between over current relays and the selection of current transformers, fuses, reclosers, circuit breaker. The characteristic of short circuit is the equivalence system impendence at the points of and in this way, shows the fault current level that is expected. The variation in the time of this faulty current is affected by the rotating machinery characteristics (Cete, 2010). The majority of
