Hydro Power

Thanks for your interest in Aartech’s offerings to the hydro power generation field. Whether you are a switchgear manufacturer, consultant, EPC contractor, project planner, system integrator or research / design / operation / maintenance / testing / commissioning engineer, we hope that you find our solutions of interest and look forward to hear from you.

Hydro Power Generation serves as important renewable source of electrical energy today and are being deployed in various capacities, from large hydro to small, mini and micro hydro plants.

ENERGY HARVESTING

Energy Harvesting solutions for micro hydro plants can enable a major change in the use of distributed energy for areas where such sources are readily available. For eg. such energy can be readily stored and used on demand to power portable handheld devices such as cell phones, radios, computers , tools, instruments etc.

Aartech’s FaraDigm™ Ultracapacitors have a wide range of ratings to suit energy harvesting requirements. Some offerings also provide for a flexible form factor, making it adaptable to the end use application very effectively.

PROCESS CONTINUITY

Process continuity for hydro generation auxiliaries are generally not considered very critical as the unit can be brought back into circuit without much loss of revenue or time. However, there could be other mechanical and hydraulic considerations that may make it important for pumps and motors to run without interruption. Sometimes, there is a need to provide startup support with DG sets and then transfer the auxiliaries to the generator after synchronization. With an experience of over 100’s of installations and decades of service, including a reference with hydro generation, Aartech’s BTS 2000 Fast Bus Transfer Systems provides proven advanced numerical microprocessor based fast bus transfer solutions of ensuring safe and reliable bus transfer operations with the best international benchmarks. These systems depend entirely on the design, operational philosophy, economy and wish-list of the end user.

Aartech is established and recognized in the field of bus transfer internationally, with several internationally published papers, approvals from major switchgear manufacturers, consultants, turnkey EPC contractors as established with performance certificates from our esteemed end users.

PROTECTION

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

CONTROL & AUTOMATION

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.

RELIABLE ENGINE STARTING

Backup DG Sets are the last line of defense against a total AC failure. However, it is observed that they may not operate on demand due to problems in the batteries, maintenance issues etc. Similarly fire engines are considered a very critical fire safety protection in such installations.

Aartech’s KranKing Utlracapacitors can provide reliable engine starting solutions to ensure robust electrical support to the batteries at the time of engine cranking. A portable jump start system can also effectively provide for an arrangement to support the operations of multiple DG sets in a DG plant.

FAULT CURRENT LIMITING

Fault levels of the MV switchboards may get compromised during re-configurations / capacity additions or operational considerations such as closing of tie breakers and grid interconnections. Even having fault levels within breaker handling capabilities, there is a considered need to reduce the fault energy, for eg. in the event of a transformer fault where severe consequential damages have been known to happen.

Aartech’s fault current limiting solutions provided as a value added system integrator of M/s G&W USA offers internationally proven CLiP® Fault Current Limiter to customers all over Asia.

LOAD LIMITING

The control arrangements in a power plant are naturally elaborate and extensive. Usually, circuit faults in the control wiring are handled by use of HRC fuses or MCBs. Both require manual intervention for restoration.

Aartech’s load limiter system solutions in the form of Load Checker can act as an automatic resettable control fuse and thus provide for minimum downtime and repair/replacement costs and efforts.
