Engineering Upgrades: A Breakdown of Our Touchpad and Touchscreen Controllers

At Dynapower, we refer to engineering upgrades as a term used to describe putting a non-original part in a machine as opposed to a repair—which refers to a like part for a like part exchange. An easy way to understand this is if you blow out your tire and replace it with the exact same tire it’s a repair whereas purchasing a higher end tire would be an upgrade.

Our main goal when considering engineering upgrades is determining how we can bring your piece of equipment that you know and love and are comfortable troubleshooting to the next level. When it comes to meeting today’s demand and production requirements, engineering upgrades to existing rectifiers are a great solution for a lot of customers.

Flywheel Systems vs. Flow Batteries

In the advanced energy storage market, lithium-ion batteries remain the primary battery technology for energy storage systems. They are used in a variety of storage applications from energy storage sited at commercial and industrial facilities to residential energy storage to multi-megawatt utility-scale energy storage installations.

Despite lithium-ion batteries’ market dominance, they aren’t the only available option. Dynapower has deployed our energy storage inverters alongside other battery technologies including flywheel systems and flow batteries. Here we take a deeper dive into how these batteries work.

SCR vs. SMPS Rectifiers: A Maintenance Perspective

Recently, we covered the three main considerations to weigh when buying a rectifier. Now, let’s dive a little deeper and shed some light a common debate in the world of rectifiers. We’re speaking of course about SCR vs SMPS rectifiers. As you will see, the ultimate differences and similarities may surprise you.

First, let’s run through the characteristics of these two classes of rectifiers. A silicon-controlled rectifier (SCR) is a semiconductor power supply that meters electricity by opening electrical “valves,” working together as a team, to rectify electricity. The longer the “valve” is open, the higher the voltage leaving the rectifier will be.

SCR rectifiers are variable voltage DC power supplies that are low frequency, high ripple systems. These systems are rugged and have a history of durability in the market – a number of our customers have systems running after 40 or 50 years. They regulate and react steadily, carry a lot of power in big copper windings, and are fairly easy to troubleshoot with large, easy-to-identify components.

Massachusetts Becomes First State to Incentivize Energy Storage Systems

Massachusetts has become the first state in the nation to incentivize behind-the-meter energy storage for commercial and industrial customers. The recent incentive–ordered by the Massachusetts Department of Public Utilities (DPU)–would allow utility companies to pay customers who agree to use their energy storage systems during peak electricity demand hours to reduce their load on the grid..

The program is being offered through an electric utilities and energy efficiency provider collaborative called Mass Save. The programs are designed for Massachusetts utilities including National Grid, Eversource, Berkshire Gas, Blackstone Gas Company and other smaller utilities in the state.

Breaking News: Energy Storage Installations Set to Soar As Battery Costs Drop

Global energy storage systems are set to grow exponentially from 9GW/17GWh deployed as of 2018 to 1,095GW/2,850GWh by 2040, according to BloombergNEF.

BNEF estimates that the 122-fold increase in energy storage will require $662 billion of investment.

In a report published on 7/31/19 by BNEF titled Energy Stoage Outlook 2019, the research company predicts a further halving of lithium-ion battery costs per kilowatt-hour by 2030.

Rectifier Repair, Engineering Upgrade & Refurbishment

Rectifiers can last decades before needing replacement. But not all parts used to build this essential piece of equipment have the same life expectancies. Some circuit boards or semiconductors degrade as part of their natural life cycle, and will need to be replaced several times in the rectifier system’s lifetime. Leaving parts at their end of life installed in the rectifier can lead to:

  • Loss of efficiency
  • Loss of communication capabilities
  • Loss of operator control
  • System failure
  • Injury or even death

When any of these conditions arise, companies need to assess the source of the issue and decide the best course of action. Customers have a variety of options to maintain their equipment. Some are by choice, and others by necessity.

Top 3 Considerations When Buying a New Rectifier

Rectifiers are power systems that convert alternating current (AC) to direct current (DC) power. The applications in which rectifiers are used are seemingly endless—with everything from metal finishing in the automotive and aerospace industries to mining, military defense and waste water treatment.

When it comes to purchasing a new rectifier or determining if it would be more cost effective to upgrade or refurbish, there are three main areas to consider: Process, environment and people.

Often, customers get lost in questions such as: Air vs. water-cooling? Switchmode or SCR type? Manual controls or PLC?

Like anything else in life, the more you put into researching and understanding the type of rectifier you need and more importantly why you need it—the more successful your operations will be.

Energy Storage Microgrids: What You Need to Know

An increased focus on grid resiliency along with the proliferation of Distributed Energy Resources (DER)—such as solar and wind—has made microgrids a very attractive alternative to the traditional centralized grid system. Before diving in deeper, though, let’s take a look at what differentiates microgrids from the traditional grid system.

Essentially, microgrids are small collections of loads controlled locally by a limited number of DERs, as opposed to large centralized power systems—which are operated and controlled from a centralized authority. Large centralized power systems maintain system stability through top down control and the aggregated inertia of the system.
