Section 2 Engineering tool set2.1 IntroductionThe structure of a monitoring and control system for electrical substations has aprinciple structure as shown in Figure 2. It contains a number of IEDs for thevarious purposes.For performance reasons, do not insert more than 150 IEDs of 650series type in one PCM600 project. In PCM600 version 2.3, themaximum number of IEDs is 60. Larger projects can be dividedinto several PCM600 projects.It can be subdivided in the three main parts:• Bay level IEDs• Station communication• Station level IEDsIEC08000101.vsdBay levelStation levelStationCommunicationStation busbayIED 1bayIED 2bayIED n-1bayIED nNCC-GW(station-IED2)PCM600(tool set)HSI(station-IED1)IEC08000101 V1 ENFigure 2: Principle structure of a monitoring and control system for a substationAll three parts require specific engineering and configuration. PCM600 is used todo the complete engineering and configuration activities needed for bay level IEDs.Product type and version specific engineering data needed by PCM600 forprotection, control and communication engineering of a particular bay IED is givenin an IED connectivity package.1MRK 511 261-UEN - Section 2Engineering tool set650 series 15Engineering Manual
