Electrical/Electronic Engineering

Project Summary

Smart Grid is the electric power network which is more reliable, more secure, more economic, environmentally friendly and safer. According to the European Regulators Group for Electricity and Gas “the smart grid is an electricity network that can efficiently integrate the behavior and actions of all users connected to it –generators, consumers and those that do both”. The key challenges of the smart grid networks are to evaluate the processes taking place in the electric power network, recognize them and make appropriate control actions. According to the proposed model of the smart grid, the location and isolation of the fault is carried out automatically. In case of the fault in the smart grid the fully automated control system should carry out the actions in the minimum possible time to recognize the fault type, to find its location, change the network configuration so that the minimum number of the higher reliability group consumers does not remain connected to the network. As a result electrical network maintenance staff obtains the information about the fault type, location and scale.

Project Objectives

The smart grid automatic control system should continually trace the state of the network and its elements, periodically perform the analysis of the reliability indexes of the electric power network and make appropriate control actions.

Whenever a fault occurs in the power generation and distributed system,the location of fault will be identified and  will be isolated from other distributed system such that black down does not occur and the supply to other areas will be on the way.Only supply to particular area will be cut off.So when the fault is remove then the supply to that area will be turned on and also to the interconnected grid system.

Due to commutations or external impact, the voltage in electrical network during transient process can exceed maximum permissible operating value. Such voltage rise (overvoltages) is dangerous to the proper operation of the equipment insulation.So we will handled that overvoltage to secure our load from damage.

Project Implementation Method

For this purpose, the fault recognition and isolation system can be used. It has the following structure:

• Fast registration of the processes and indexes (faulted line, fault place, stationary and transient processes of voltages and currents);

• Transmit the registered data to the control terminal; Control terminal, which has permanent communication link with dispatching center, stores the registered data, performs analysis of the situation and selects the optimal post fault configuration of the electricity distribution network;

• Control terminal independently or after permission of the dispatching center performs necessary control actions or network switching.

Fault analysis aims to determine the causes that have led to certain failures (especially repetitive breakdowns and those with a high cost) to take preventive measures to avoid that. The improvement of the maintenance results goes,necessarily, from studying the incidents that occur on the plant and bringing solutions to avoid them.Common causes of failure are usually one or more of

these four:

1. Material Failure

2. Human mistake by the Operation Staff

3. Human Mistake by Maintenance Staff

4. Abnormal External Conditions

Benefits of the Project

Our propose project will integrate the following elements:

The registration and automatic characteristics analysis of fast electromagnetic processes, overvoltages, overcurrents and non-stationary disturbances;

One phase to ground fault detection after the insulation damage in distribution network with an insulated or compensated neutral;

 One phase to ground fault spot location according to the initial current transient process in the distribution network with cable and overhead lines;

The control of the resource of the equipment insulation.

Our propose model will indicate the fault location and isolate them from interconncecting system so that supply will not be cut off to other areas,only supply to particular area will be cut off.So when the fault location will be identified we will eliminate it within the time so that we will continue the supply to our area.

Technical Details of Final Deliverable

The purpsoed hardware is the one of the best approach towards the power generation failure deetction.The purposed project eliminiates the specific fault area to minimize the power breakdown issues.This hardware helps us in real time situation about the eliminatio of faulty areas from the system to avoid the possibel loss.The hardware will helps us to monitor and controll the faulty location in the transmission and distribution line,
