Application functions

The IEDs are very flexible and may include a wide range of protection and con-

trol functions. Many of these are included as basic in the "ready-to-use" IED.

The IED is delivered with a basic configuration that includes default parameter

settings. This simplifies the initial start-up of the IED. In the IED 670 series the

following examples are preconfigured default functions, included and set to

typical values: Id > (PDIF, 87), Z< (PDIS, 21), Zpsb (RPSB, 78), O->I

(RREC, 79), 3U< (PTUV, 27). These are set to ON. The default setting for

backup functions is OFF.

The configuration is available under the Basic template for the IED or can be

uploaded into the structure with the configuration tool. By default, a number of

signals are associated with the disturbance report and will show up on the dis-

play and be recorded as disturbance records. It is always possible to return to

the default configuration if problems with a specific configuration arise. IO

configurations are order specific and are therefore not included in the default

configuration. To activate inputs and outputs, configure them with the Signal

Matrix tool. For help, refer to the configuration tool section in this document.

Each protection function has a function block with both analog and binary

inputs and outputs. The function blocks are described in detail in the Technical

reference manual. The analog inputs are connected by default to a pre-process-

ing analog block in the configuration and a cross reference table is generated in

the parameter setting tool (PST) which is part of the PCM 600. Ensure that the

analog signals connected to the function blocks are checked so that the correct

inputs are fed with analog signals when testing. Binary signals are connected

with the configuration tool.

A number of logical elements are available giving the user enough flexibility to

create his own applications. OR gates are useful as several signals cannot be

connected to one input. An OR gate then allows the user to tie any combination

to a single binary output or functional input. OR gates also allow a combination

of signals such as the creation of alarm groups which are connected to IO ports.

Consider also the debug possibilities where the status can be seen on-line since

this can be very useful when testing is performed. Each ordered function can be

included in the configuration with the configuration tool, but can also be left in

the library for future use. How to test the functions is described in the Installa-

tion and commissioning manual.
