Power Transmission

The transmission utilities need to ensure that the grid interconnection requirements are satisfied by their connected users. Renewables penetration, particularly Wind Power have a distinct impact on reactive power requirements which vary as per wind speeds. While these can be compensated broadly at an individual wind turbine level, there can be substantial difference in the reactive power needs at the Point of Common Coupling (PCC) due to the combined effects of all wind turbines, transformers, transmission lines etc. Railway traction substations source variable reactive power from the grid connection during train transits. Metal industries draw highly fluctuating currents at poor power factor and standard compensation cannot avoid problems such as voltage flickers which can be a major consumer irritant.

Aartech is associated as a value added system integrator with M/s S&C USA for their PureWave DSTATCOM , a proven power quality product with a large and successful installation base worldwide.

S&C’s PureWave DSTATCOM Distributed Static Compensator is a fast-compensating reactive power source that is applied on the transmission or distribution system to reduce voltage variations such as sags, surges, and flicker, along with instability caused by rapidly varying reactive power demand. PureWave DSTATCOM can also help provide quick recovery for the transmission system after contingency events such as loss of part of the system or individual equipment.

Electrical infrastructure is experiencing unprecedented growth in several developing regions of the world. The management of this infrastructure layout however demands key capabilities in design, engineering, procurement, manufacturing, system integration, installation, erection, testing, commissioning and facility management.

For building modern power transmission infrastructure, Aartech offers a range of Unitized Substations as per customer specific requirements to take care of key logistical challenges. Aartech utilizes its experience, networking and knowledge in the electrical infrastructure space, and works with its customers to understand their requirements, suggest value added features and facilities and provide turnkey end-to-end solutions for unitized power management in coordination with in-house resources as well as strategic business partners around the world.

A complete range of powerful yet economic, state-of-the-art microprocessor based protection solutions for a variety of standard substation protection as well as special customer defined schemes that require integration of features such as standard protection with special requirements such as synchrophasors, islanding, bus transfer, load shedding, synchronization, SCADA interface and automation, developed through international collaboration are offered by Aartech’s Relay SSD.

Aartech’s Control & Relay Panels (CRP) SSD is organized to offer specialized custom built, integrated software engineered solutions involving aspects of protection, metering, communications and control for distributed automation, SCADA and remote telemetry based control and automation solutions.
