IIOT Connectivity Made Easy – PICs

From |

As industries advance towards future technology, businesses have to constantly keep themselves up to date. Failure to comply may result in two major repercussions:

  1. Slow adopters will see themselves lagging behind competitors
  2. Late adopters may see a rise in the prices to install these new technologies

IIOT, or the Industrial Internet of Things, is not a new term. Regrettably, many companies are still not developing sound approaches to adopt them.

Take for example refineries. Traditional data analytics such as spreadsheets are still being used to analyze processes and trends; using historic data to make operational decisions.

Interior of process plant

Refineries store millions of databases and at times it becomes challenging for engineers to extract information from a cesspool of data. To make matters worse, varying branches of the organization may utilize foreign systems which proved difficult when systems needs integration.
As a result, refineries are considered to be data rich but in hindsight, information poor.

I’ve got 99 problems

In a traditional data-analytic methodology, it is acceptable for engineers to find themselves stranded with missing data. The solution? Most rely on “Experience” or so-called intuition to solve their engineering woes and make “informed” decisions. Guilty as it might seem, ask any engineer who have worked in refineries and they might just confess to using this ‘archaic’ technique.

Refineries of the future (or refineries who will sustain in the future) will need to change a different tack towards how they organize their data. Engineers can employ advance data analytics to analyze and make comparisons to several vital parameters (such as temperature, pressure reading and flow data) that makes use of varying systems that have diverse data formats, all in real time.

Smart factory

Advance data analytics can run audits and identify data correlation among the different results and in any case if a deviation in the results of the data were to emerge, engineers will be notified immediately, in real time.

For example, it is common for an instrument’s pressure reading to fluctuate. Instrument’s pressure reading could also irregularly plunge due to ordinary situations such as a spike in production. However, leakages along the pipeline could also cause pressure readings to drop.
With advance data analytics, engineers are able to determine if such major shifts are justified.

Easier Said than Done?

Adopting new technology always come with anxieties. It is always easier said than done. Although the idea of running advanced data analytics may seem ideal, it is not without its challenges.

In order for all the varying hardware to get connected, it has to comply with a single universal format that allows data to be unified. This might be expensive if you need to hook up current legacy hardware to new technologies that may not have the compatible specifications to begin with.

Shunt Reactor Controller

Shunt reactor controller

Shunt reactor

What is a shunt reactor controller? I recall having the same question running through my head when a customer told us about what he was trying to do. Well, before knowing what a shunt reactor controller does, let us look at what exactly is a shunt reactor?

Some of you might wonder “Why does it look like a transformer?”. Yes, you are right, to a certain extent, because a shunt reactor does have similarities with a transformer in terms of its construction. However, they are both very different in terms of their functionality.

While a transformer is used to efficiently transfer power from one voltage system to another to cater for the application required, a shunt reactor absorbs reactive power generated from the source i.e. motors, generators etc.

Active and Reactive Power

What is reactive power and why do we bother to absorb? That might be the next question to ask. Before going into that, we need to understand that in an AC circuit, there are both active power (or real power) as well as reactive power, in which the active power is used to power up a system. To understand this from another perspective, think of it as a pint of beer where the beer is your active power and the reactive power is the foam.

The Beer Analogy of Active and Reactive Power

Let’s put water piping system as an analogy to electric circuit, and voltage is the ‘water pressure’. A certain level of water pressure is required in order for the water to travel across the piping system to the designated location to perform certain task, such as flushing your toilet bowl. Similarly, voltage plays the same role in an electric circuit to ensure that active power can be supplied to run any equipment or device. In this case, reactive power is the key element to maintain the voltage level in a circuitry.

Hence, instead of using the word ‘absorbing reactive power’, shunt reactor is rather used to stabilize or compensate the level of reactive power in an electric system.

From Component to Solution

Rewinding back a little on how this shunt reactor controller came about. It started with a normal enquiry sent in, asking for a voltage transducer. We followed up with a visit to the customer to understand further.

He showed us the solution that he was going to implement for his end user who runs a palm oil refinery. This was an existing solution in another plant where it was used to control the output of power that being transferred back to the grid from the bio-gas generation using the effluent of palm oil.

  • During the day, when most of the equipment in the plant is running, the whole electric system is highly loaded and more reactive power is consumed. Thus the causing the voltage to drop.
  • However, whenever there is less equipment running, less reactive power is consumed and hence the voltage increase.
  • This is the time when a shunt reactor has to be switched on to compensate the reactive power in order to maintain the voltage level at a particular rating.
  • Each shunt reactor has a fixed rating. Hence, putting several shunt reactors together and adding controls to it can achieve different reactive power compensation at one time, depending on the system load.
  • This whole solution is the basic working concept behind a variable shunt reactor, however cost is always a concern when it comes to such solution.

His idea was to duplicate the same solution in his project. Looking at the pictures he showed us, we believed that it was possible to be implemented with the range of products that Phoenix Contact has to offer. Hence we came up with the solution concept diagram with a brief program flow.

Customized solution from Phoenix Contact

We finally secured the project after a few rounds of discussion and modification to suit best to his application. The list of products that are put into this solution includes:

  1. ILC 171 controller – The processing unit to control the shunt reactor via relay and contactor.
  2. MCR voltage transducer – The main component to take in voltage from the system and convert it to readable value for the controller.
  3. UNO power supply – Main power source to the controller and other peripherals.
  4. TP 3150 Touch Panel – Serve as a HMI for the user to control the shunt reactor controller and display of current value of the system.

Marine-certified HMI

Marine-certified

Salt and water are the natural enemies of most man-made product and in any marine environment, you will find these in abundance. Saltwater will corrode all manners of metal over time. Therefore, to qualify for marine certification, any product has to pass stringent test.

Consequently, for any insurance to be arranged or licenses to be issued, it is necessary for ships and off-shore platforms to be surveyed and certified to international and/or national regulations by one of the marine classification boards.

To fulfill such exacting requirements, Phoenix Contact offers the TPM 3000 series Touch Panels. Designed for maritime applications, these Human Machine Interfaces (HMI) were specially tested and approved for shipbuilding.

Available in a range of sizes (4.3″, 5.7″, 7″, 10.4″, 12.1″ and 15″), each model features two buttons for dimming the display brightness, an external horn, and on the rear, a floating output for connecting external signal generators.

PI Seminar in Bangkok

From |

The PI Association Southeast Asia conducted a Profibus / Profinet Seminar in Bangkok, Thailand on 4th September 2014. Coincidentally, during the same period, there was also another event held in Bangkok called the Oil & Gas Thailand (OGET) from 2nd – 4th September 2014.

 

Coming up to this event, I was really a little worried whether the turn out for this event was going to be good due to the other event. Even though the online registrations were fully booked, sometimes, you never know!
