Date(s):
July 17, 2025
Venue:
Northwest Public Power Association
Description:

Who Should Attend: 

Engineers and technical personnel involved in the interconnection process of residential and small commercial distributed generation resources (i.e. Solar and battery energy storage system (BESS). The attendees will learn what to look for in an application for interconnection, National Electrical Code (NEC) requirements for the systems and maintaining power quality for the electric utility. The class is designed for technicians with some higher-level application issues for engineers.

Distribution Engineering Series: Overcurrent Protection - July 15-16, 2025

Overview: 

Solar and BESS systems are becoming more common, and utilities need to be well versed in the requirements of IEEE 1547 and the requirements of the NEC related to these systems. This course will focus on inverter-based systems such solar and BESS. Material to be covered includes NEC Article 690, signage requirements, grounding requirements, and common control schemes for BESS technology. The IEEE standard 1547 for interconnection will be discussed for understanding of the goals and the requirements of the standard. A complicating factor are the programmable smart-inverters and the options for programming and verification will be presented. Common screening tools used for small, distributed resources will be presented along possible solutions for those systems that fail the screening. The course will include case studies using real world applications.
