The voltage control also resulted in reduced reactive MVar demand on two of the three generators, with the slack bus experiencing a decrease of In addition to these features, Simulator boasts integrated economic dispatch, area transaction economic analysis, power transfer distribution factor PTDF computation, short circuit analysis and contingency analysis, all accessible through a consistent and colourful visual interface.

Substatikn other commercially available power flow packages, however, Simulator allows the user to visualize the system through the use of full-colour animated oneline diagrams with full zooming and panning capability. Simulation technique is very useful in the power system planning and design.

The power is then fed into a 33KV bus from which different loads were tapped. There are four bus types in a power transmission network.

In a power flow network, buses are bound to have self- or mutual admittance, and this increase the complexity to determine the admittance of the bus. Aubstation 11 KV bus feed the power to different 11 KV feeders. Power flow study also known as load flow constitutes an important part of power system analysis and design of any power system network. Transmission lines are power lines that connect buses. This functionality may be useful, for example, in illustrating the diavram issues associated with industry restructuring.

This makes Simulator sinhle useful as a standalone power flow analysis package. These features are so well integrated that you will be up and running within minutes of installation. Equation-1 shows an example of an admittance matrix. The pie charts associated with each transmission line, provide the student with an indication of transmission substationn loading. Such a problem solution practice is called power flow analysis. The power flow solution is used to evaluate the bus voltage, branch current, real power flow, reactive power flow for the specified generation and load conditions.


Also, because of the low computation requirements of the contouring algorithm, the algorithm is implemented into a real-time animation of the voltage profile of a power system. There are three types of loads in power system.

The power flows real and imaginary for this example are in the same direction. There is a one KV main bus. A load in a power system context is defined as devices that consume power in the network.

At its core is a comprehensive, robust Power Flow Solution engine capable of efficiently solving systems of up to 60, buses. The different kinds of faults are also simulated at various buses of the substation.

For a steady state load flow study, parameters that generators are represented as substatioon fixed power and desired voltage magnitude. Premium Membership Premium membership gives you an access to specialized technical articles and extra premium content electrical guides and software. Reference [2] considered the kV Nigeria power grid for estimating the real and reactive power flows, power losses in the entire network and bus phase angles using Power World Simulator.

Transmission lines may be switched in or out of service, new transmission or generation may be added, and new transactions may be established, all with a few mouse clicks.

Electrical Design Of /33KV Substation | EEP

Load, generation, and interchange schedule variations over time may be prescribed, and the resulting changes in power system conditions may be visualized. The most of electrical power is generated by three main methods: At this KV bus eight KV lines are sinlge. It is very necessary to carry out power flow analysis for satisfactory operation of the power system. Facebook Linkedin Google Plus Twitter.


These are principle components of a power network; other components such as compensator are usually included only to improve the network after load flow studies. The PowerWorld simulator is a user friendly tool that provides visual simulation results.

Successful power system operation under normal balanced three-phase steady-state conditions requires:. Simulator is actually a number of integrated products. The content is copyrighted to EEP and may not be reproduced on other websites.

In reference [3] an attempt has been made to investigate power flow in the northern NigeriakVtransmission sub — grid using Power World software.

A power system network usually consists of component such as buses, transmission lines, generators and loads. The simulation and analysis includes power flow analysis and short circuit analysis.

The load is supplied at various voltage levels. The power flow was run using Gauss — Siedel power flow algorithm and low voltage violations were found at buses 1, 7, 8, 9, 10, and The resulting bus voltages and phase angles are shown on the one-line diagram.

The resulting power flows for each transmission line feeding the connected load are also displayed.

Simulation and Analysis of 220kV Substation

Bus represents reference node during calculation or simply nodes that are used in nodal analysis. They are purely resistive load, purely reactive load and load that consume both type of power.

The red line indicates the KV bus section.

The design of the entire substation was made keeping in mind the most basic requirements of a proper substation including the civil and domestic requirements. By using the PowerWorld simulator we also analyse the effect of adding or removal of transmission line and other power system component.
