Energy saving and asset surveys have been around for many years, typically when it comes to Variable Speed Drives or Motors, this is something undertaken by the local sales rep, who will spend a few hours on site collecting motor and load details, then input them into the VSD manufacturers online tool which will predict given savings for a given reduction in motor speed.
This approach is ok when you are looking to sell more VSDs, however at best it is only a 2D picture in a 3D world. It can be a good indicator as to which applications should be focused on, however it cannot accurately tell you at which speed the motor and system perform the best, nor can it tell you what effects the new equipment will have on the rest of your networks harmonics or power factor.
Quantum Controls have for many years offered a more in depth solution by backing up these surveys with hire trials, whereby you get black and white results with regards to the energy savings available, you measure the energy consumption as it is today, then measure again whilst under the new method which is simulated through the use of temporary hire equipment.
We have added a new type of Survey to our wide range of services and we are running a first come first served special offer! Free survey to the first 10 readers who email email@example.com to request a survey. As we said there are only 10 available at this special price, so get in touch as soon as you can.
The Q360 Energy Survey looks at all aspects of the site surround the use of VSDs and power quality, considering all impacts the equipment can have on the site, and looking at all avenues of potential risk and rewards available, with or without the need to purchase new equipment. For £650 we will do a full days audit split into 5 main sections, integrating all of the key areas:
1. Power Quality
We analyse the power factor and harmonics on site as well as the transformer loading %, we also look at the bill and work out what you could save by improving the power quality, in this section will be general information on harmonics and PF, and what it means to the supply, plus site specific information based on what we found.
2. Asset Integrity
We look at the existing assets, and their age, lifecycle position, maintenance history, failure history and general condition, in this section we group the assets into categories, active obsolete, soon to be obsolete etc, and give them a colour coded rating of what would be most damaging in the event of a failure, which items are the highest risk and would take the most work to repair / replace in the event of a breakdown. Recommendations will be made with regards to longevity of the asset life and risk exposure.
3. Asset Optimisation
We have a look at the settings and setup of the VSDs to see how they are running, and we again make recommendation based on changing the control of the assets you already have to ensure they are getting the most out of them, both in terms or process control and energy efficiency, looking at things like parallel pumping, flux optimisation, duty standby control, PID control etc.
4. Energy saving upgrades
This section of the survey would look at where upgrading and replacing assets would offer then an increase in energy efficiency, more in line with your typical energy report, however we will use our three phase logger to show what the load is right now, and predictions based on anticipated savings, the recommendations on this would be along the lines of hires to prove savings, or quotes for the upgrade where its beyond doubt.
5. Observations and Recommendations
This is an overview of the above sections with recommendations given financial savings, and also general engineers observations, such as filter media was dirty in all panels, or panels we excessively hot etc.
It will also bring all sections of the report together, in that we will consider the impact on Harmonics and power factor that the recommended VSDs will have, we will also offer guidance on where we feel the biggest benefits will be found and prioritise the actions recommended.
