GalleryInverter-Based Resources Reactive Power Capabilities
This is the third of five articles in the series “Reactive Power in Utility-Scale Solar PV Applications.” Here’s the last article – “Reactive Power and Transmission & Distribution Operations” – in case you need to catch up.
Inverters are a key component of any Inverter-Based Resources (IBR) facility, including utility-scale solar PV. Because of their ability […]
GalleryNew Free Course Announcement: Construction Communication Methodology
Construction communication methodology is a critical, yet rarely discussed, element that shapes the overall outcomes of a construction project and the experiences of those working there. With the countless timely needs that require our focus on construction projects, it can be difficult to be intentional about the way we communicate. Nonetheless, communication strongly impacts everyone’s […]
GalleryReactive Power and Transmission & Distribution Operations
This is the second of five articles in the series “Reactive Power in Utility-Scale Solar PV Applications.”
In Part 1 of this series, we looked at the differences and relationship between real, reactive, and apparent power. We also looked at the production and absorption of reactive power by equipment such as transformers, reactors, and capacitors.
Before we […]
GalleryWhat Are Reactive Power and VArs?
This is the first of five articles in the series “Reactive Power in Utility-Scale Solar PV Applications.”
Right after I started my first job out of college, I found myself presenting at a meeting and talking about reactive power and VArs. These were very senior-level engineers, and, although I didn’t recognize it at the time, never […]
The Most Important Factors When Specifying a Transformer
Going from designing residential solar systems to commercial and industrial (C&I) solar systems requires new knowledge in many areas. One area in particular is equipment selection. When megawatt-scale solar systems are designed and put into operation, medium voltage electrical equipment must be properly selected for safe and optimal operation. In this excerpt from Megawatt Design, […]
