Unlocking More Value from Wind Energy Through Smart Monitoring

As the global demand for renewable energy intensifies, wind farms are emerging as pivotal players in the transition to sustainable power sources. In 2023, the wind industry added a remarkable 117 gigawatts (GW) of global capacity, underscoring its growing significance in the energy landscape. However, to maintain and accelerate this momentum, ensuring the efficient operation and maintenance of wind farms is paramount. Traditional reactive maintenance approaches are proving inadequate, necessitating a shift towards smart monitoring...

Overhead T&D, Direct Current Technology

Direct current (DC) is the preferred technology for moving large amounts of power across long distances. DC results in overall higher efficiency and reliability than an equivalently-sized alternating current (AC) system moving the same amount of power.

The Advantages of DC

More efficient: Over long distances, DC transmission can move more power with less electrical losses than an equivalent AC transmission line.

Lower Cost: Higher efficiency means a lower transmission cost, helping renewable energy compete against other power sources.

Improved Reliability: HVDC transmission can enhance system stability, allow the operator complete control over power flow, and facilitate the integration of wind from different resource areas.

Smaller Footprint: DC transmission lines require narrower right-of-way footprints, using less land, than equivalent AC lines.

The major advantage of DC power lines is their efficiency—less energy is lost as it is transmitted and there is no need for reactive compensation along the line. Because...
