11. Functions of ari device

• determination of the power-off state of line;

• control of good condition of chains of tension;

• control of the included or power-off position of switches;

• functions of TARI, OARI, FARI depending on time of defense or type of disconnecting;

• control of switch readiness to carry out a cycle to "on-off ";

• to carry out the next algorithms of functioning ARI:

  • one phase ARI(OARI) at the action of defense;

  • ARI with control of absence of tension on lines and presences of tension on tires;

  • ARI with control of absence of tension on tires and presence of tension on a line;

  • ARI with control of symmetry of tension and presence of synchronism;

  • ARI without the presence of control;

  • control of synchronism for one switch, including the corner of difference of phases, differences of frequencies and control of tensions.

12. Device of fixing disconnecting and including line (fld and fli))

A device must have next functions:

• fixing of line disconnecting before FARI;

• fixing of line disconnecting after failure FARI;

• fixing of line repair on the state switches with one or on either side of line;

• functioning in fact with disconnecting of both switches;

• possibility of functioning at operating of defense WL on disconnecting of three phases of WL;

• possibility of working in fact of reception signal on communication channel in case of setting off line from an opposite end;

• possibility of confirmation of disconnecting on absence of current of line;

• fixing of line including after repair at the place of setting device FLD and on either side of line;

Device must provide:

• possibility of setting device and change internal configuration of automation by a programmatic method with a protection fetch;

• blocking of discrete device outputs at his damage;

• signaling of wearing-out, his disrepairs;

• registration of emergency parameters and wearing-outs with synchronization of time on the signals of GPS;

• support of protocol of MEK 61850, and presence of standard international protocols of exchange by information for integration in ACS;

13. Automation device of liquidation asynchronous mode (adla)

Functional requirements ADLA:

• Presence of three electoral organs which work independently and operate on the separate groups of output relays:

• angular;

• impedance;

• current.

• A presence of independent groups of output chains (discrete logical outputs of type are a "dry contact") is not less than two contacts for every stage.

• Possibility of input the programmatic blocking from a false wearing-out:

• on possible speed of change of corner;

• by maximally legitimate value of tension (currents) of reverse and zero sequence;

• by maximally legitimate value of current of positive-sequence.

• Presence of blocking at:

• removal and serve of operative current, and also at the interruptions of feed of any duration with next renewal;

• chain contactor`s of operative current.

• Presence of internal recorder emergency events with energyindependent memory.

• Presence of signaling and state of disrepair.
