Description of configuration REC670

REC670 is used for the control, protection, and monitoring of different types of bays in power networks.

The IED is especially suitable for applications in control systems with distributed control IEDs in all bays with high demands on reliability.

The IED can be used up to the highest voltage levels.

It is suitable for the control of all apparatuses in any type of switchgear arrangement.

The control is performed from remote (SCADA/Station) through the communication bus or from local HMI.

Different control configurations can be used, and one control IED can be used per bay or one IED can be common for several bays.

Interlocking modules are available for all common types of switchgear arrangements.

The control is based on the selection before executing the principle to give the highest possible security.

A synchronism control function is available to interlock breaker closing.

A synchronizing function where the breaker closes at the right instance in asynchronous networks is also provided.

A number of protection functions are available for flexibility in use for different station types and busbar arrangements.

The auto-reclose for single-, two-, and/or three-phase reclose includes priority circuits for multi-breaker arrangements.

It cooperates with the synchro check function with high-speed or delayed reclosing.

Several breaker failure functions are included to provide a breaker failure function independent from the protection IEDs, also for a complete one- and a half breaker diameter.

High set instantaneous phase and earth overcurrent, 4 steps directional or nondirectional delayed phase, and earth overcurrent, thermal overload, and two-step under- and overvoltage functions are examples of the available functions allowing the user to fulfill any application requirement.

Disturbance recording and fault locators are available to allow independent postfault analysis after primary disturbances with a single failure in the protection system.

6 x 32 dual-directional channels for a winter trip and binary signals transfer are available on each included communication card in the communication between selected IEDs inside the station or in a nearby station.

The advanced logic capability, where the user logic is prepared with a graphical tool, allows special applications such as the automatic opening of disconnectors in multibreaker arrangements, closing of breaker rings, load transfer logics, and so on.

The graphical configuration tool ensures simple and fast testing and commissioning.

The wide application flexibility makes this product an excellent choice for both new installations and the refurbishment of existing installations.

Description of configuration REC670

This configuration is used in single breaker arrangements with single or double

busbar.

The control, measuring, and interlocking are fully configured including communication with other bays such as other lines and the bus coupler over GOOSE.

The typical line bay has been configured but project templates including several bays plus the bus coupler are available in an exported PCM600 project and can be downloaded to replace the default configuration.

The following should be noted. This connection diagram shows the connection with the basic supplied single binary input and binary output boards.

In many cases this is sufficient, in other cases, for example with full control of all apparatuses included, more IO cards are required.

Our proposal for a full version with control is to use two Binary input modules and one Binary output module.
