Power Systems Fault Analysis and Protection
Dafam Fortuna Hotel, Yogyakarta | 09 – 12 Agustus 2016 | IDR 7,000,000
DESCRIPTION
The addition of new power system facilities, e.g., power plants, lines, new loads, etc. complicate the power network. Faults occur frequently in all parts of the system. As producers and users of Electrical Energy, you must increase your awareness of present and future power system protection. System integrity depends on a well conceived and properly implemented protection philosophy. It is important to learn how to design a system where equipment or line removal and system restoration occur quickly and reliably. To do this, it is essential to understand how present mechanical and microprocessor-based relaying systems function, how they communicate, how their performance can be analyzed and what are the future challenges. Protection system’s main function is to clear faults from the power system in high speed to: enhance people’s safety and minimize equipment damage and maintain power system stability. Protection of power systems requires an understanding of system faults and their detection, and the safe isolation of the faulted device from the system. This course covers the analysis of power system faults for small and large scale systems. This will be followed by the basic protection functions and their applications to the protection of all elements of power systems. The course emphasizes advanced protection schemes required for practical systems experienced in industrial plants, distribution, transmission and generation systems.
WHO SHOULD ATTEND
The course is designed for the power systems engineers responsible for the operation, control and protection of distribution, transmission and generation systems. It is also targeting consulting and manufacturing engineers, engineers in industrial plants, etc.
