SmartValve increases transfer capacity on existing lines by gigawatts

Before SmartValve

A simplified planning scenario predicts a network constraint.

After the loss of one line, unequal loading on the remaining lines limits network utilization to 40%. Although the thermal capacity is 3000 MW, the maximum usable capacity is restricted to 1200 MW.

After SmartValve

Power is PUSHED & PULLED to lines with spare capacity.

By balancing flows, transfer capacity is increased to 3000 MW even after accounting for the loss of any one line. Maximum utilization is achieved by small applications on multiple circuits.

SmartValve is the next logical step in the progression of FACTSs (Flexible Alternating Current Transmission Systems).

Prior SSSC (Static Synchronous Series Compensator) installations have required custom designs, series injection transformers and considerable substation space. SmartValve offers a move away from custom engineering towards a modular, standard offering that eliminates these disadvantages.

SmartValve is a single-phase, modular-SSSC that injects a leading or lagging voltage in quadrature with the line current. This means it can increase or decrease power flows on a circuit and perform dynamic services. Distinct from legacy SSSCs, SmartValve is transformerless and uses an integrated, fast-acting bypass for protection from system faults. A SmartValve deployment is connected in series with a utility facility, operates at line potential and has no connection to ground.

SmartValve is a modular, transformerless SSSC, with an integrated fast-acting bypass and flexible deployment and control.

Safety & Reliability

Rest assured on your highest priority

“We value human life and health above all else and take actions to maintain the safety of our products, employees, customers, workplace and community.”

Smart Wires Guiding Principle

Our engineering is guided by a rigorous commitment to FMECA (Failure Mode, Effects and Criticality Analysis) and Safety-in-Design (SiD).

We use Military Standard “MIL-STD-1629” as the source for our FMECA process. This bottom-up approach to risk assessment analyzes every system and sub-system based on their failure modes and quantifies criticality based on likelihood and severity. Our FMECA process is informed by subject matter experts in the fields of electrical engineering, mechanical engineering, mechatronics, chemical engineering, power systems, power electronics and structural engineering.

SiD integrates hazard identification and risk assessment into every layer of the engineering process. SiD is a systematic, structured approach to analyze human and environmental interfaces with products. This process eliminates or minimizes the risk of injury throughout the product lifecycle, ensuring a safe system during testing, manufacturing, installation, operation, maintenance and de-commissioning.

This relentless commitment to safety and reliability is validated through our field history: zero safety incidents and an industry-leading product availability metric.

Adaptability & Speed

Quickly solve your grid's changing problems

The energy transition has introduced new complexities which have driven an unprecedented transformation of the power sector. These radical changes have challenged traditional approaches to planning and operating the grid.

By identifying new ways to make power flow, the grid itself becomes a solution to these problems. Critically, this must be done while respecting power security, reliability, efficiency and affordability.

In order to address these challenges, SmartValve offers versatility in installation and operation. Utilities pursue various deployment methods based on the need duration and space available. Since SmartValve injects voltage independent of line current, several control modes are possible. SmartValve can output a fixed reactance, a fixed voltage or control line current within a given range.

SmartValve is quick to deploy, easy to relocate or scale, and fully controllable, providing the adaptability utilities need given the challenges they face today.

Installation needs vary

Towers can replace an existing structure or new towers can be placed mid-span. Existing towers can also be modified.

 

Works well if:

  • Lack of substation space
  • Aging infrastructure replacements already planned.

High-density deployment built within or adjacent to right-of-way or substation.

Works well if:

  • Insufficient space for legacy power flow controllers
  • Seeking larger power flow impact.

Containerized option that can be assembled in 4 hours and fully commissioned in 1 day.

 

Works well if:

  • Needs are short-term or emergent in nature.

Versatility in operation

SmartValve injects voltage independently of line current. This increases its effective reactance injection when operated below its rated current.

SmartValve can output at any point in its operating range offers a variety of control modes:

Fixed reactance - Insufficient space for legacy power flow controllers

Fixed voltage - Injected reactance varies as the line current changes.

Current control - Line current is kept within a given operating range.

These control modes can each be configured with a variety of pre-determined set points.
