TELVENT

The laboratory deployed at TELVENT is designed to test and demonstrate the logic processing and distributed interaction as designed for IDE4L FLISR solution based on IEC61850 GOOSE messages exchange, the correct selection of configuration parameters and the remote updating process for the communication schemes and operation settings by means of an IEC61850 MMS client.

The benefits of the lab deployment in TELVENT is that will allow to test and validate the logic implementation, the signal processing and the communications between devices before the field deployment, thus reducing the time that it will be needed in the field demo for installation, startup and collecting data.

Additionally, once the validation for the different demo sites have been performed, the lab deployment will be used to get data from different test scenarios allowing the comparison of results with the ones obtained for traditional schemes.

Within the IDE4L project, Telvent has developed a specific cabinet for FLISR testing and validation. This cabinet emulates a loop distribution grid provided with a primary substation and four secondary substations.

Each substation is provided with a FLISR IED and two controllable power interruption devices which position is monitored with specific light devices.

Power service provided to the lines controlled by each secondary substation is also monitored by means of light indicators.

In order to emulate faults, the cabinet is provided with push bottoms in different positions of the grid that cause short-circuits increasing the current sensed by the IEDs according to their location.

IDE4L FLISR specific solution considers the existence of two interruption technologies along MV lines, deploying two steps IED interactions to control their operations. Cabinet interruption devices could behave as reclosers or switches, thus allowing the testing of different deployment configurations.

All the IEDs are connected through an Ethernet LAN using a network switch where IEDs are able to exchange information regarding the fault event over GOOSE protocol. A monitoring PC is also connected to the switch allowing the logging and analysis of the GOOSE messages to determine correct operation and response timing for different phases of FLISR operation.

On the service restoration phase, PC IEC 61850 simulation suites will be used to generate MMS messages for FLISR communication scheme and setting reconfiguration, testing the ability to adapt for the new grid topology.
