NPT BAY (9.2)  Bay Control Unit

NPT BAY (9.2) Bay control unit manufactured by LLC EnergyindustryAvtomatization is a multipurpose device that provides acquisition and processing of analog and discrete data on the facility's status as well as switchgear control.

    NPT BAY Connection Controller supports all the functions necessary for operation within a digital substation. The connection controller allows transmission of data by means of IEC 61850-8-1 (MMS) protocol to the top level of the system, data exchange with other devices and remote RTUs using IEC 61850-8-1 (GOOSE) protocol, receive IEC 61850-9-2 data from multiplexer units. NPT BAY also supports all the functions necessary for operation within a traditional substation framework, including acquisition of discrete data with the help of discrete input modules, transmission of controlling commands with the help of relay-controller output modules, acquisition of analog data from traditional CT (1/5 A) and VT (100 V). NPT BAY bay control unit allows integration of other devices lacking IEC 61850 support by means of serial interfaces. This function allows use of such devices in the integrated information environment using IEC 61850 standard.     

Advantages for creation of Digital Substation:

• Support for IEC 61850-8-1 standard for communication with the upper level of the APCS;

• Possibility to receive and send GOOSE messages, including those for acquisition of discrete data and transmission of control commands;

• Possibility to receive and process IEC 61850-9-2/9-2LE data.

Main functions:

• Switchgear units status control;

• Calculation of mode parameters from CT and VT;

• Operative interlocking of switchgear units;

• Local control over switchgear units from a control panel;

• Remote control over switchgear units from SCADA system;

• Fault oscillography;

• Support for freely programmable logics following 61131 standard.

 Volume of controlled data:

 Unlimited, if digital connections are used.

Data exchange protocols supported:

• IEC 61850-8-1 (MMS) – data exchange with SCADA system, Telemechanics;

• IEC 61850-8-1(GOOSE) – data exchange with SCADA system, RPA, EA, Telemechanics;

• IEC 61850-9-2(Sampled Values) – measurement data reception from digital current and voltage transformers;

• IEC 60870-5-104 data exchange with Telemechanics subsystem, integration of devices;

• IEC 60870-5-101 data exchange with Telemechanics subsystem, integration of devices;

• IEC 60870-5-103  integration of devices;

• Modbus-RTU – integration of devices;

• Modbus-TCP – integration of devices.
