Paralleling Switchgear: Documenting The Sequence of Operation with Charts Loads
The sequence of operation for a paralleling switchgear project can be complex. Because no two power systems are exactly the same, each should be custom-designed to meet the requirements and challenges associated with the project application. To reduce guesswork and ambiguity during system design and operation, Kohler Power Systems has developed sequence charts that document […]
Sizing Generators For Motor Starting: A Practical Guide to Understanding How Motor-Starting Loads Affect Generator Performance
Today’s standby power loads are more complex than ever before. In many industrial and commercial applications, standby generator must supply power to a mixture of linear and nonlinear loads in addition to large motor loads that cycle on and off. Of all the diverse loads a standby generator must supply, applications with motors present the […]
Managing Emergency Generators With Nonlinear Loads
In this paper we will be focusing on the harmonic distortion that occurs in an emergency power solution. The source of this harmonic distortion will be specifically from nonlinear loads. By the end of this paper you will be able to understand the effects of nonlinear loads and its advantages, enabling you to create better […]
Power Up with A Load-Management System: Setting Up a Load-Management System Part 3
There can be many differences between load-management systems, but common design practices and setup procedures can be applied to most systems and applications. The following are functional descriptions, configuration tips and example scenarios for some of the more common techniques for load management: Startup shed Generator online load add kW capacity load add Engine failure […]
Power Up with A Load-Management System: Setting Up a Load-Management System Part 2
While load-management setup is application-specific and depends on facility engineers to determine triggers to activate load management, there are four questions to answer in the process that are consistent for any setup: Which loads need to be managed? What is the load priority order? How will the loads be shed? How is load shed coordinated?
Power Up with A Load-Management System: Identifying Load-Management System Applications Part 1
Load-management systems can improve flexibility, versatility and power quality of a power generation system. This three-part series explores tips for setting up load-management systems along with guidelines for seven load-management methods. This first installment focuses on appropriate applications of load-management systems where controlling load priorities can improve power quality to critical loads.
