Power flow and Contingency Analysis of SEPCO Region Based on Grid Code using Power System Simulator
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryIn current complicated societies, the effective and continuous electrical energy supply is fundamental part. The power systems in current eras are being pushed to function nearer to the limits because of the integration of enhanced consumption of energy and different obstructions kinds to the extension of available transmission system. The secured power system is that which keeps in the restricted limits just after subjected to the disturbance or having security of power system is the most challenging and complicated tasks to the engineers of power system, so assessment of security is taken place to attain the complete data regarding impact of electrical component outage e.g., Contingency in the main system.
It is substantial that the simulations of system are taken place to recognize the services necessary for assuring the power system in forthcoming eras to accomplish the secure, economic, and safe whole system operation.
In this project we have performed the load flow and contingency analysis of SEPCO region following NEPRA grid codes using simulator of power system for PSS/E software. The studies that we have performed using PSS/E includes load flow analysis, contingency analysis (N-1), PV and Qv analysis for voltage stability and dynamic stability analysis on specified network of SEPCO.
These simulation studies are carried out for planning purpose, after doing these analysis we are able to find out the exact state of the system, losses in the system, weak busses in the system, and effects of any small or large disturbance in the system and other factors that contribute to make the system unstable.
The main goal of this studies is to perform these simulations and find all the factors that may contribute to make the SEPCO region unstable in future. These planning studies not only help us to design the secure and stable system but also save millions in case of any credible contingency.
- To design the actual model and will be performed in PSS/E software.
- To enable planning engineers to identify hotspots where possible grid violations may occur.
- To identify the weak busses in the network using Contour analysis in PSS/E.
- To suggest remedial actions such as installation of capacitor banks and synchronous condensers.
- To perform the PV and QV analysis to overcome the voltage instability problems.
- Dynamic analysis will be done to over to protect the system in case of any sever disturbance.
- Fault analysis is done with the help of Dynamic simulation.
- Critical Clearing time and critical clearing angle are determined in case of any fault in the system.
This research and designed analysis model will enable different distribution companies for smooth power supply and fault predication or identification before any unawanted condition damage the supply of power. Distribution networks are used in different areas to meet the customer's demands for energy. The analysis enables one for simulating unplanned and planned outages, along this enable the operator to estimate the load flow over the transformers, voltage profile, and transmission lines of system buses, and implement the remedial solutions in the distribution networks to transport electricity to each customer's residence, business, or industrial plant. The key implemetation of this project is in contoll system of ditribution companies that will ensure the faultless system.
