Equation-1 shows an example dizgram an admittance matrix. The power flows real and imaginary for this example are in the same direction. In reference [3] an attempt has been made lind investigate power flow in the northern NigeriakVtransmission sub — grid using Power World software. 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.

Therefore, the entire system is modelled as electric networks and a solution is simulated using a digital program.

The contouring routines are implemented into the Power World Simulator software package, with results shown for systems with up to several thousand buses. The results of load flow analysis are used in load forecasting, system planning and operation. Experiments and interviews with system engineers are also discussed to measure the applicability of voltage contouring as an add-on to practical Energy Management Systems.

The transformers used are transformer number 3, 4, 6.

## Simulation and Analysis of 220kV Substation

For the power flow analysis using the single line diagram of KV substation, the model of the substation is developed in the Power World Simulator. Transmission lines are power lines that connect buses.

The voltage control also resulted in reduced reactive MVar demand on two of the three generators, with the slack bus experiencing a decrease of Load, generation, and interchange schedule variations over time may be prescribed, and the resulting changes in power system conditions may be visualized. The pie charts associated with each transmission line, provide the student substarion an indication of transmission line loading.

### Electrical Design Of /33KV Substation | EEP

The approach to the modelling and the analysis of large-scale power flow solutions are presented in this thesis. These are principle components of a power network; other components such as compensator are usually substatkon only to improve the network after load flow studies.

The different kinds of faults are also simulated at various buses of the substation.

They are purely resistive load, purely reactive load and load that consume both type of power. At this KV bus eight KV lines are connected. Depending on the requirement the loads are subdtation on and off.

The resulting bus voltages and phase angles are shown on the one-line diagram. All this lines are export and import power to the substation. The power is then fed into a 33KV bus from which different loads subsration tapped.

A load in a power system context is defined as devices that consume power in the network. This functionality may be useful, for example, in illustrating the many issues associated with industry restructuring.

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. Such a problem solution practice is called power flow analysis.

This program computes the voltage magnitude and angle at each bus in a power system under balanced three-phase steady-state sibstation. Substantial losses occurred along some transmission lines like Osogbo-Aiyede In order to solve for the power flow solutions, it is necessary to model all the networks, generators, transformers and shunt capacitors.

The PowerWorld simulator also gives information for what amount of power the system works with maximum efficiency. The power flow solution is used to evaluate the bus voltage, branch ljne, real power flow, reactive xiagram flow for the specified generation and load conditions.

We considered incoming power at KV and the power was transferred to main bus through isolator-circuit breaker-isolator combination. Bus represents reference node during calculation or simply nodes that are used in nodal analysis. The simulation result of the existing kV power grid indicates that Damaturu and Gombe bus voltages were out of tolerance with per unit and actual values of 0.

Generator 1 was set up to be the slack generator i. The basic formula to solve all load flow problems is represented by Equation 2 and Equation-3.
