Review of Ground Fault Protection Methods for Grounded, Ungrounded, and Compensated Distribution Systems
This paper reviews ground fault protection and detection methods for distribution systems. First, we review and compare medium-voltage distribution-system grounding methods. Next, we describe directional elements suitable to provide ground fault protection in solidlyand lowimpedance grounded distribution systems. We then analyze the behavior of ungrounded systems under ground fault conditions a...
متن کاملFault inductance based protection for DC distribution systems
The fault protection is a critical element to ensure the reliable and secure operation of DC distribution systems. Most DC distribution systems are tightly coupled systems with low line impedances which may result in fast current increase during a fault. Thus, it is challenging to develop a fast and reliable DC fault protection method. This paper proposes and develops a novel fault inductance b...
متن کاملA Novel Ground Fault Non-Directional Selective Protection Method for Ungrounded Distribution Networks
This paper presents a new selective and non-directional protection method to detect ground faults in neutral isolated power systems. The new proposed method is based on the comparison of the rms value of the residual current of all the lines connected to a bus, and it is able to determine the line with ground defect. Additionally, this method can be used for the protection of secondary substati...
متن کاملFault simulation environment for power distribution networks with protection operation
Nowadays research and development of power networks towards a new, more intelligent and self-management infrastructure is a topic of great interest, becoming what is known as Smart Grids. In order to achieve all this, programming tools to deal with large volumes of information are required, to model and simulate these future networks. This paper presents a tool that allows to model distribution...
متن کاملFault Location Techniques for Distribution Systems
Faulted lines must be repaired and returned to service in the shortest possible time to provide reliable service to the customers. Fault locators provide estimate for both sustained and transient faults. Transient faults cause minor damage that is not easily visible on inspection. Fault locators help identify those locations for early repairs to prevent recurrence and consequent major damages. ...
