8 Converter Structure

The converter is divided into two sections: the P34x section and the RIO section. Both sections consist ofseveral function blocks. The converter comes up in the standard view; the RIOplus section and thetemplate controller section can only be seen in the advanced view.

8.1 P34x Section

The P34xsection is divided into four groups: the Relay Parameter Section, the Additional Informationsection, the RIO Plussection and the TemplateControllersection.

8.1.1 Relay Parameter Section

The Relay Parameter Sectionincludes the parameters which have to be changed by the user. All relayparameters are included in this section and have to be set to the actual relay values. The parameters aregrouped and named as in the AREVA MiCOM S1 Studio software. Each parameter in this block isidentified by a Foreign ID (witch corresponds to the Address in the relay software).

8.1.2 Additional Information

This block contains additional data for testing the P34x relay functionality. The block is divided into thefollowing sections:

General section includes detailed information needed for the test report like manufacturer,device type, substation name etc. This section includes parameters which have to be changed bythe user according to the customer relay type and substation.

Relay Informationsection - This block has been added for relay specific parameters such astolerances which cannot be set by the user, because they are constant values. All values set inthis block can be found in the "P34x Generator Protection Relay" manual. Typically, these blocksdo not have to be changed, as they are already set to the values given in the user manual of the

relay. Circuit Breaker Informationsection includes information which is required for the CB test.

Test Tolerancesection includes an additional test tolerance to calculate the start and end valuefor trip and pickup tests by using theOMICRON TU Rampingmodule.

Test Parameterssection includes additional test parameters for testing adaptive functionswitch are not directly supported by the OMICRON TU test modules e.g. a voltage level for the 51Vtests. Furthermore it includes additional test parameters which are needed for testing theprotection function but not found in the relay settings. e.g. high operating current stage for the 87Phase Differential protection function. This section includes parameters which have to bechanged by the user.
