Section 3 REG630 variants3.1 Presentation of preconfigurationsThe 630 series protection relays are offered with optional factory-madepreconfigurations for various applications. The preconfigurations contribute to fastercommissioning and less engineering of the protection relay. The preconfigurationsinclude default functionality typically needed for a specific application. Eachpreconfiguration is adaptable using the Protection and Control IED ManagerPCM600. By adapting the preconfiguration the protection relay can be configured tosuit the particular application.The adaptation of the preconfiguration may include adding or removing of protection,control and other functions according to the specific application, changing of thedefault parameter settings, configuration of the default alarms and event recordersettings including the texts shown in the HMI, configuration of the LEDs and functionbuttons, and adaptation of the default single-line diagram.In addition, the adaptation of the preconfiguration always includes communicationengineering to configure the communication according to the functionality of theprotection relay. The communication engineering is done using the communicationconfiguration function of PCM600.If none of the offered preconfigurations fulfill the needs of the intended area ofapplication, 630 series protection relays can also be ordered without anypreconfiguration. In this case the protection relay needs to be configured from theground up.The functional diagrams are divided into sections which each constitute onefunctional entity. The external connections are also divided into sections. Only therelevant connections for a particular functional entity are presented in each section.Protection function blocks are part of the functional diagram. They are identifiedbased on their IEC 61850 name but the IEC based symbol and the ANSI functionnumber are also included. Some function blocks, such as PHHPTOC, are used severaltimes in the configuration. To separate the blocks from each other, the IEC 61850name, IEC symbol and ANSI function number are appended with a running number,an instance number, from one onwards.1MRS757582 C Section 3REG630 variantsREG630 21Application Manual
