Voltage Regulation and Power Quality
New Enclosure and FlexDG Mode Add Versatility to SEL-2431 Voltage Regulator Control
The versatile SEL-2431 Voltage Regulator Control can now be ordered with an enclosure.
The enclosure can be configured with SEL precise-timing devices and radio-ready communications equipment already installed, allowing you to order them together with the SEL-2431 as a pre-engineered solution.
Deploying the SEL-2431 in a dedicated cabinet also offers an easier modernization path toward advanced distribution management system (ADMS) integration and system-level volt/VAR optimization.
With its recently added FlexDG mode, the SEL-2431 is an ideal choice for systems that incorporate multiple distributed energy resources (DERs), in which it may be unclear whether reverse power flow is coming from the traditional power source or DERs. The SEL-2431 with FlexDG has several benefits:
- It automatically identifies the source of a reverse power flow, whether traditional generation or a cogeneration site, and regulates voltage in the correct direction.
- The device makes faster voltage regulation decisions with fewer incorrect taps.
- FlexDG can be installed as a free firmware upgrade in most currently existing SEL-2431 units.
