Implementation of Interlocking Scheme for Bus bar and Arc Protection Using IEC 61850

The main scope of the thesis is to focus on bus bar protection in the medium voltage level. It is important for designing the protection setup according to the intended protection scheme, planning for circumvent the arc fault and set up the protecting device in a required manner. In this thesis there are different protection schemes for the bus bar have studied. The arc incident has discussed and put emphasis on the process of arc development. For mitigating the arc faults and other unwanted fault incident, it is important to have a co-ordination between the protecting devices. IEC 61850 is an important protocol of communication that has discussed from the basic idea. In the thesis it has given effort on the implementation of bus bar protection scheme with the protection devices in the substation. Those devices are communicating with each other for exchanging the GOOSE message using IEC 61850. The protection devices are connected with arc sensor and getting the input signal from it. A proposed design scenario has implemented with different fault situation in different location. The thesis has given the idea about the protection scheme of bus bar implementation in a medium voltage substation perspective. It is also helps to understand how the protection devices are working and communicating with each other via GOOSE message. The thesis is also able to demonstrate the role of protection scheme on the bus bar and the co-ordination of protective devices for implementation of the scheme. It has also ability to accommodate the arc flash sensor which increases the protection sensitivity
