Renewable energy sources  

 

Photovoltaic Solutions

 

With support and experience from Control Techniques, we supply the technology & service for high effiency power conversion and control solutions for photovotanics energy schemes.

 

Power conversion system are designed to maximise effiency across varying radiation intensities, typical achieving 97% to 98% with maximum power Point tracking (MPPT).

 

The system was build in redundancy by inverter modularity. If one inverter is unavailable due to servicing or failure, the other modules continue to operate thus minimizing lost power generation. If your requirements change, your system can be designed for future expansion to increase capacity.

 

The grid tie inverters achieve a high quality sinusoidal output with only 1 to 2% total harmonic votage distotion THD(V). This allows compliance with local harmonics regulation for conection to the public electricity supply.

 

Water & Water Treatment

Water companies are under unprecedented presure from rising energy cost as well as legislative and clime change. Developing strategies to reduce operating costs whilst optimising the performance of asset is critical.

 

We provide new sollution to enhance conectivity, reduce energy consumption, minimise downtime and to react inteligent to real problem as they occur.

 

The Inteligent Pump control drives system deliver measuable improvements in pumping reliability , up time and performance.  A long standing pumping problem suffer by water companies is that of ragging, the fouling of pumps impellers in waste water systems.  Manually clearing the problem is a costly and unpleasant task requiring a maintenance team and frequently a crane. Downtime may extend to serveral days during which time the back up systems are under additional pressure. A total system failure can result in effuent leakage with implications for the enviroment, human health, clean –up cost and breaches of legislation.

 

The system is also able to schedule real time pipe scouring cycles, detect deteriorating flow and potentioal impeller wear.

 

Our system also have the remote monitoring using a click in Ethernet option module. This enable access to live pump performance operational views and data collection off site.

 

Installing variable speed drives to control pup flows to match operation demand, can significantly contribute to a reduction in energy consumption and improve process control. In some applications, inteligent system are able to further reduce energy cost by operating during off peak tariffs.
