This is a statu quo that many professionals, who have entered the substation automation world in the last decade or so, have found as a given fact, with little chance to influence the development of the standards at a moment when the committees, and the relatively limited number of experts who do most of the real work, were already long-established and functioning steadily. Perhaps that is why, sometimes, utilities try ‘shortcuts’ such as talking directly to vendors or creating user groups. I think this is specially true regarding IEC 61850.<br /><br />In fact there is a widespread belief in the utilities’ domain that IEC 61850, along with its expected yields, is failing to take off. How long have we been hearing about IEC 61850? And yet many SA managers will tell you that, although IEC 61850 is definitely likeable, they cannot go decidedly into the standard because, at the present moment, it does not offer a measurable increase in productivity. What is paradoxical is that a huge productivity boost is lying asleep at the heart of the very concept of IEC 61850, in the form of standardised configuration. It was not any ‘user group’ that decided to integrate the configuration (FC=CF, SP) data, not just the process data, within the IEC 61850 data model! It was not any ‘user group’ that decided to create SCL as a way to fix and standardise the configuration information that an IED needs! That is why to read, in IEC 61850-6, clause 5, that ‘each manufacturer is completely free to find the best way in supporting engineers by a specific software tool’ is a real damper, an absolute wet blanket. To put it blankly, it seems as if IEC 61850 were ‘afraid of itself’.<br /><br />People from the manufacturer side, although they offer an incredible amount of expertise and a deep knowledge of the technical intricacies, cannot always see the problems that the users face when administering a multi-vendor installation. Learning how to use 10 or 12 different vendor-specific tools is an effort that gives absolutely no value to the user. On top of that, with the advent of IEC 61850, many manufacturers have decided to just wrap the IED in an IEC 61850 ‘shell’, so that the configuration process entails the traditional tasks on the specific tool plus the new IEC 61850 tasks which are carried out by a completely different procedure, to the extent of even disregarding the CID file and/or requiring another software tool or a new module that is, in fact, another tool since it has not been integrated in a global, seamless design. In short, the configuration tools and tasks, far from getting fewer and simpler, have doubled. Instead of moving forward, we seem to be moving backward. As a consequence, when stepping into a multi-vendor IEC 61850 system you are risking a noticeable waste of resources and therefore, as said above, a notorious challenge to productivity. <br /><br />On the contrary, standardised configuration shall allow the user to:<br /><br />1) Dispose of the specific vendor tools and related training of maintenance personnel (people not always remarkably ready to get familiar with a new HMI at 4 in the morning)<br /><br />2) Implement a seamless top-down approach (therefore simpler, more consistent and less error-prone) for all the stages of SA lifecycle: from the SCD to the CIDs, and CIDs directly into the IEDs<br /><br />It is thus the opinion of a growing number of people in the utility side that the general acceptance of the advantages of standardised configuration by the whole IEC 61850 community is only a question of time. It is just too good an idea to forgo (moreover, one that is absolutely in tune with the principles and spirit of the standard). It is too good an opportunity to miss.<br /><br />Regards,<br />Julio Dominguez<br />(from the E3 Group)Anonymousnoreply@blogger.com
