Power System Protection
Introduction
This course covers the fundamentals of protecting a power system against hazards posed by abnormal system conditions, such as short-circuit faults. An overview of the protective devices available for application, both industrial and utility, is presented along with typical means of implementing these devices. Both electromechanical and digital relays are discussed. Fuse selection and coordination is explored in depth. Utility-specific protective devices, such as reclosers and sectionalizers, are presented, and utility-specific protection strategies, such as fuse-saving and fuse-blowing, are covered.
This training course will feature:
- Philosophy of protective relaying and protection strategies
- Electromechanical relay operating principles and microprocessor implementations
- Radial system protection – time-coordinated overcurrent protection
- Instrument transformers
- Differential and distance relays, including pilot protection
Objectives
By the end of this course, participants will be able to:
- Comprehend protective relaying philosophies and choose appropriate protection strategies
- Understand how electromechanical relays work and how they are emulated by microprocessors
- Design a properly-coordinated overcurrent protection system for a radial distribution system
- Properly specify instrument transformers for protection applications
- Design protection schemes utilizing differential and distance relays, including pilot protection
Utility Distribution System Planning
Introduction
This training course covers the process of planning an electrical utility distribution system to assure adequacy, reliability, and economy. The course begins with an overview of the distribution system and its basic equipment. Next, the planning process is explored, step-by-step, emphasizing the importance of each step in achieving the desired outcome. An in-depth view of engineering economics is included to assure cost-effectiveness of the capital-intensive infrastructure. Since the planning process is necessitated due to changes in load, the process of performing and interpreting load forecasts is investigated. Finally, means of quantifying and measuring reliability will be presented so the reliability of the distribution can be properly assessed.
Utility customers today are demanding higher reliability and lower costs, and this trend will undoubtedly continue for the next several decades. Effective planning techniques provide a means of meeting the customer demands of reliability and economy while better positioning the utility for adapting to future customer requirements. This training course presents proven planning methods which will benefit both the utility and its customers.
This training course will feature:
- Distribution System and Equipment Overview
- The Planning Process
- Engineering Economics
- Load Forecasting
- Reliability Assessment
Objectives
By the end of this course, participants will be able to:
- Specify optimum distribution system topologies and equipment
- Conduct comprehensive planning studies
- Perform the calculations necessary to economically justify system improvement projects
- Implement and interpret load forecasts for distribution system studies
- Quantify reliability and assess progress toward achieving reliability goals
