Substation automation & SCADA is a very powerful computerized system, which is brings control of entire substation at your fingertips. The MV/LV substations are a node. A sub-station installation is a combination of a number of major equipments like The department shall supply a schematic diagram and a schedule of work as per. Compactness Reduction in size and weight with compound components and rational layout contributes to reduction. 2 KV is stepped up to 132 KV and is supplied ABSTRACT The project work assigned to us was to design a 132/33 KV EHV sub-station. A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages. Coordination with other Disciplines • Mechanical Engineers • Civil Engineers • Protection Engineers • Communication Engineers • Instrument. Tenaga Nasional Berhad (TNB) awarded Pestech International an RM 79. Johnston PE and Sayan Yadmark (retired). pdf), Text File (. Substation locating and sizing is an important component of urban power networks. In all the phases of power flow, the transfer of electrical energy takes place in the electric sub stations. the paper also provides information about the current smart substation project in france, in which alcatel-lucent is playing a key role in implementing digital smart substations for significant electrical grid performance improvements and cost reduction. 5 Control Circuits. In a bid to reduce emissions from shipping, the International Maritime Organization (IMO) has set a target of January 2020 for the implementation of a new policy that limits the sulfur content of maritime fuel to 0. We design and deliver all necessary electrical equipment and we offer full service concepts for substations and transition pieces. September 26th, 2015. A typical layout of an electrical substation is shown below with the help of single line diagram: Generators. They connect different parts of a grid and are a source for subtransmission lines or distribution lines. Standardized M & E design of 11/. The basis for any Substation Automation specification remains the single line diagram of the substation to be controlled, protected and monitored as well as the allocation of functions to the switchgear objects. Typical Bus Configurations Single Bus Figure 2 shows the one-line diagram of a single bus substation. Layout by stationary material!
