Solutions in the Context of Automatic Frequency Load Shedding

With regard to automatic frequency load shedding, the decentralization of power generation has made a change of strategy mandatory. Thus, the operators of transmission networks, together with distribution network operators, have agreed upon a restructuring of automatic frequency load shedding in the form of a mandatory, comprehensive, decentralized and self-sufficient structure which also takes into account the current power feed-in situation.

In their product portfolio, IDS GmbH offers solutions both for automatic and for manual load shedding acc. to § 13.2.

IDS Products in Practice

Frequency-Protection Devices for Automatic Frequency Load Shedding

The frequency protection functions for automatic frequency load shedding demanded by FNN are implemented in the compact protection devices ACOS 353 and ACOS 354 as well as in the protection devices ACOS 333 und ACOS 334. The active power direction detector prevents tripping in the event of a re-injection of power, thereby preventing a deterioration of the power generation situation in the event of an automatic or a manual disconnection. Tripping is indicated via an event signal in order to be able to distinguish it from a breake tripping or other activities of the protection system.

The ACOS 750 Station Automation System

The current settings of frequency steps, tripping and reverse injection signals as well as blocking commands are communicated to the control center via the station automation system and are also incorporated into local processing functions and the logic (e.g. interlocking, switching priority). In station automation, the products HIGH-VIS SAS are used as station control terminals or ACOS 750 as automation system.

The IDS HIGH-LEIT SCADA System and CAIGOS-GIS

In the event of a load shed, consumers and generators, respectively, are disconnected from the grid. The affected medium-voltage sectors can be immediately identified in the SCADA system HIGH-LEIT. Visualization of the low-voltage sections that are no longer supplied, and of the affected consumers and generators is done via CAIGOS-GIS.

ACOS EEM for Automatic and Manual Load Shedding

The application ACOS EEM for feed-in management is activated both in the event of manual and automatic load shedding. Whereas manual load shedding is initiated via an announcement and the non-discriminatory selection of feeders, the latter does not take place in the case of automatic load shedding via automatic frequency load shedding function.
