forming principle diagrams. The external connections to primary devices are also

shown, stating the default connections to measuring transformers. The positive

measuring direction of directional protection functions is towards the outgoing feeder.

The functional diagrams are divided into sections with each section constituting

one functional entity. The external connections are also divided into sections. Only

the relevant connections for a particular functional entity are presented in each

section.

Protection function blocks are part of the functional diagram. They are identified

based on their IEC 61850 name but the IEC based symbol and the ANSI function

number are also included. Some function blocks, such as PHHPTOC, are used

several times in the configuration. To separate the blocks from each other, the IEC

61850 name, IEC symbol and ANSI function number are appended with a running

number, that is an instance number, from one upwards. If the block has no suffix

after the IEC or ANSI symbol, the function block has been used, that is,

instantiated, only once. The IED's internal functionality and the external

connections are separated with a dashed line presenting the IED's physical casing.

Signal Matrix and Application Configuration

With Signal Matrix and Application Configuration in PCM600, it is possible to

modify the standard configuration according to the actual needs. The IED is

delivered from the factory with default connections described in the functional

diagrams for binary inputs, binary outputs, function-to-function connections and

alarm LEDs. The Signal Matrix is used for GOOSE signal input engineering and

for making cross-references between the physical I/O signals and the function

blocks. The Signal Matrix tool cannot be used for adding or removing function

blocks, for example, GOOSE receive function blocks. The Application

Configuration tool is used for these kind of operations. If a function block is

removed with Application Configuration, the function related data disappears from

the menus as well as from the 61850 data model, with the exception of some basic

function blocks, which are mandatory and thus cannot be removed from the IED

configuration by removing them from the Application Configuration.
