Automate Your Switching Processes with a Two-Way Network

Capacitor banks control the level of voltage supplied by minimizing voltage drops and absorbing energy from a line spike. With a two-way network that communicates with capacitor banks at the substation, utilities can automate switching processes, maintaining voltage levels and minimizing VAR losses.

SecureMesh WAN broadband solutions, part of the Trilliant Communications Platform, provide an optimal solution for communication with capacitor banks. Our cost-effective SecureMesh Connectors provide local Ethernet connectivity, linking remote reclosers with always-on, low-latency wireless communications. Every link is encrypted for security.

With the SecureMesh WAN providing networking for the distribution grid, your Smart Grid deployment can provide cost-effective communications to capacitor banks and integrate into SCADA and distribution management systems (DMS).

With a Smart Grid network extended to capacitor banks, you’ll see improvements in grid reliability, visibility into critical load information, better asset management, reduced O&M costs, and improved customer satisfaction.

Volt/VAR Optimization

Capacitor banks control the level of voltage supplied by minimizing voltage drops  and absorbing energy from a line spike. The banks also provide Volt / VAR Control by switching in capacitor banks to compensate for VAR losses when large inductive loads occur, such as when air conditioners, furnaces, dryers, and/or industrial equipment start.

With a two-way network configured to communicate with capacitor banks at the substation, utilities can automate the process of switching in capacitor banks to maintain voltage levels and minimize VAR losses. By integrating centralizing capacitor bank control with a Distribution Management System (DMS), distribution networking provides:

  • Centralized ability to switch bank in and out of operation
  • Centralized monitoring and reporting

From a communications perspective, capacitor banks do not require much bandwidth and are latency tolerant but benefit from always-on connectivity to enhance grid reliability.

The SecureMesh WAN products provide an optimal solution for communication with capacitor banks. SecureMesh Connectors are cost-effective outdoor wireless devices that provide local Ethernet connectivity, either for a direct Ethernet connection or for a serial connection via a Ethernet-to-serial adapter, that enables communication via both legacy protocols (DNP3, Modbus) as well as TCP/IP. Each SecureMesh Connector provides long-range links (up to 7.5 miles apart) to connect remote reclosers with always-on and low-latency wireless communications. In addition, every link is encrypted for security and recloser communications can be partitioned into virtual private networks (VPNs) for additional security and traffic guarantees.

With the SecureMesh WAN providing networking for the distribution grid, the Smart Grid deployment can provide cost-effective communications to capacitor banks and integrate into SCADA and distribution management systems (DMS). Extending a Smart Grid network to capacitor banks results in improvements in grid reliability (i.e. lower SAIDI, MAIFI, CAIDI, SAIFI metrics), visibility into critical load information, asset management, and operations and maintenance costs, which also results in improvements in customer satisfaction.

With a Smart Grid extended to provide capacitor bank control and monitoring, utilities improve grid reliability, improve VAR control, improved asset management, and reduced operations and maintenance costs.
