Description

The REF615 is offered in nine distinct standard configurations. Modifications to the standard signal configuration can be implemented via the graphical signal matrix or the graphical application functionality within the Protection and Control IED Manager (PCM600). Furthermore, PCM600’s application configuration feature enables the development of multi-layer logic functions, leveraging a variety of logical components such as timers and flip-flops. By integrating protection functions with logic function blocks, the IED configuration can be tailored to meet user-specific application requirements.

Through the Signal Matrix and Application Configuration tools in PCM600, adjustments to the standard configuration can be made to align with actual operational needs. The IED is shipped from the factory with default connections, which are detailed in the functional diagrams covering binary inputs, binary outputs, function-to-function connections, and alarm LEDs. The Signal Matrix is utilized for GOOSE signal input engineering, as well as for establishing cross-references between physical I/O signals and function blocks. Notably, the Signal Matrix tool does not support the addition or removal of function blocks—such as GOOSE receive function blocks—with these operations instead handled by the Application Configuration tool. If a function block is removed using the Application Configuration tool, the associated function-related data will be deleted from both the menus and the 61850 data model. An exception applies to certain basic function blocks, which are mandatory and cannot be removed from the IED configuration via the Application Configuration tool.

For overcurrent and short-circuit protection, the REF615 provides four overcurrent stages. The instantaneous stage (PHIPTOC1) can be blocked by activating binary input 1 (X120:1-2). Two negative sequence overcurrent stages (NSPTOC1 and NSPTOC2) are included to address phase unbalance protection needs. The output (BLK2H) of the inrush detection block (INRPHAR1) offers two capabilities: it can either block the function or adjust the active settings of any of the aforementioned protection function blocks by means of multiplication.

All operate signals are connected to both the Master Trip and the alarm LEDs. LED 1 serves as the operate indicator for overcurrent protection, while LED 4 functions as the operate indicator for both negative-sequence overcurrent protection and phase discontinuity protection.
