Integrated Volt/VAr Management Systems (IVVM)
There are theoretical and practical principal aspects related to Integrating Volt/VAr Management strategies that are consistent with Smart Grid objectives for Asset Management and Reliability in the distribution system. Integrated Volt/VAr Management (IVVM) of LTC transformer control, line regulator control along feeders, pole top capacitor bank control (remotely controlled and locally controlled), power quality issue mitigation for sags, swells, and harmonics, adherence to CBEMA voltage waveform criteria, as well as protection of the intertie with disbursed, alternative, or green energy sources, may all be part of a smart grid strategy. Beckwith Electric is a leader in implementing the components of such a strategy. With Beckwith’s long standing history of IVVM, we have implemented system performance enhancements, such as the use of Autodaptive® techniques, VAr Biasing, Line Drop Compensation (LDC), flattening the voltage profile end to end and Conservation Voltage Control, as well as advanced techniques for paralleling of single bus, double bus and ring bus configurations. Beckwith has also developed SCADA heartbeat integrity checks, and automatic change over algorithms on loss of communications to enhance system reliability. Beckwith Electric has kept abreast of industry advances in communications, ports, protocols and media and the use of Ethernet over fiber optics, IEC 61850, mesh networks, reporting by exception and unsolicited reporting, broadcasting capabilities for voltage collapse mitigation, distribution VAr support to transmission side for voltage collapse mitigation, and much more.

Beckwith Electric is the premier leader in voltage and VAr management techniques and has the system elements that facilitate the solutions for strategies that our utility customers want. Our 42 years of experience in IVVM, coupled with thousands of man-hours of experience, instill confidence in the solutions that we provide. Let Beckwith Electric be your Smart Grid partner for implementing your integrated volt/VAr management strategy!

Benefits of Integrated Volt/VAr Management (IVVM)

• Improved system stability
• Reduced system-wide losses
• Increased power delivery capacity (kW)
• Minimized voltage variations, resulting in satisfactory delivery voltage to customers
• Reduced maintenance costs
• Reduced/deferred capital expenditure
• Reduced operating costs
• Flattened Voltage Profiles and Conservation Voltage Control (CVC)

Reduction Of Line Losses the Fundamental Key
Studies have shown that line losses in the distribution system approach 8 to 10%, and that correct and proper capacitor bank placement and operation can reduce line losses in the distribution system by as much as 1 to 2%.

For example, if the annual load of a distribution system is 35,000GWh/yr, 8% line losses would equate to 2,800GWh/yr.
At a cost of $0.05/kWh, the 2.8x109 kWh/yr would be a $140 million dollar loss annually.

If proper and correct placement and operation of switched capacitor banks in the distribution system can conservatively reduce line losses by 1% of the annual load, then the annual savings from installing pole top cap banks exceeds $17 million.
(1/8 of 2,800GWh/yr = 350GWh/yr or 350,000,000 kWh/yr @ $0.05/kWh = $17.5 million savings annually).

Savings like this can largely defer or offset the need for additional generation by freeing up delivery capacity.

With more capacitance in the system, the x/r ratio of the lines are reduced which can improve stability with less voltage fluctuations (with x/r = 4, 1kw produces a 1 volt drop while 1 kVAr produces a 4 volt drop).

With less voltage variations, better voltage delivery to customers can also be achieved.

With flatter voltage profiles, conservation voltage control can be utilized, which can reduce loading system-wide, which in turn also frees up delivery capacity and again can defer or offset capital expenditure.

It’s a beautiful thing, let Beckwith Electric show you how…

Protection Systems
Protection Systems feature the use of IPS (Integrated Protection Systems¨)÷ microprocessor-based relays which use digital signal processing technology to provide protective relaying functions for generator, transformer, or intertie protection. Each relay provides ãpick and chooseä protective functions, which allow users to select functions to customize relays for their specific application needs. Each Integrated Protection System also includes the IPScom¨ Communications Software for monitoring and recording capabilities, and offers options such as IPSplot¨ Oscillograph Analysis Software to display and print oscillographic data, a Human-Machine Interface module to provide local operation and metering, a Target module with target and output LEDs, and a redundant power supply. Protection Systems can be housed in enclosure cabinets. Learn More

Motor Bus Transfer Systems
The utility-grade Syncrotran System consists of a Transfer Logic Controller and a Power Transfer Relay. The system performs all of the necessary logic and control functions for the motor bus transfers in two directions by automatically selecting from either fast, in-phase or residual voltage methods. The relays allow the Transfer Logic controller to supervise a fast transfer by monitoring the phase angle between the motor bus and the new source, blocking transfer if the angle is excessive. If fast transfer is impossible because of excessive angle, the Power Transfer Relay offers the option of closing the motor bus in-phase with the new source at the next pass through zero degrees. Should system conditions prevent transfer by either method, the Transfer Logic Controller contains a circuit that measures bus voltage, regardless of the frequency, and allows a residual transfer to occur when the motor bus voltage has decayed to a safe level.

Synchronizing Systems
Synchronizing Systems are designed to provide both a manual and an automatic synchronizing function for one generator or multiple generator breakers. Control switches in the front panel provide for manual raising and lowering of both speed and voltage of the generator in order to match the frequency and voltage prior to synchronizing. Digital frequency meters and volt-meters provide both generator and bus measurements. An operator is assisted during manual synchronizing by both a synchroscope and synchronizing lights. Synchronizing Systems typically include: a Generator Control Unit that automatically matches generator frequency and voltage levels to those of the bus; a Syncrocloser Unit that sends the closing command to the breaker to provide breaker closure at the precise moment of phase coincident; and a Syncrocloser Check relay that provides a permissive function, verifying that voltage and phase angle conditions are within preset limits before allowing the breaker to close.

LTC Transformer Control And Paralleling Systems
Extending the life of some of your most valuable assets can be problematic when the original equipment supplier no longer exists or supports the control device. Many times, it makes sense to upgrade your outdated substation transformer or regulator control system. Beckwith Electricâs LTC Control Systems are designed by Beckwith Systems Engineering to be used with load tap changing transformers or regulators having various types of load tapchanger mechanisms (old to new). Enclosure designs range from customer-specified to standard NEMA enclosures. Each system utilizing the M-2001C Tapchanger Control includes an Adapter Panel that matches the unit being retrofitted. Enclosures can also integrate the associated control switches for local control, auxiliary relays, test jacks, convenience outlets, paralleling schemes and even dial-up analog cellular to facilitate site-specific remote control. Your choice of paralleling schemes include: circulating current method, DVAR1 method, DVAR2 method, Daisy-Chain, and Daisy Chain Wireless. (Both types of Daisy Chain paralleling are only available with Autodaptive¨ LTC controls.) Our engineers will help you decide which is best for your application. Learn More >>
