System of monitoring and management shchsn

The system of monitoring is intended for control of the equipment of own needs of alternating current. It represents the distributed network of programmable controllers and devices of input-output of the signals united by digital communications on the basis of Ethernet and RS-485.

The local microprocessor system of monitoring and control allows to carry out integration of ShchSN under the standard protocol to industrial control system of any power facility.

With ShchSN discrete signals of position of automatic switches, signals of malfunction and analog signals of controlled parameters are given.

Installation of the local device of registration of analog and discrete signals in normal and emergency operation of work of ShchSN is possible. Support of the MEK 61850 protocol is realized.

Functions of system:

1. Measurement, indication and control of parameters:

- tension and current -

- position of the ShchSN-switching equipment

- analog signals of controlled parameters.

2. Formation of signals with delivery of the alarm system in the form of "dry" contacts:

- a signal of the general accident -

- malfunction of system of monitoring -

- other generalized and logical signals.

3. Formation of archive of discrete events and periodic record of a cut in analog sizes with time tag. Synchronization of hours with industrial control system under the NTP protocol.

4. Ostsillografirovaniye of emergency processes with a frequency of 2 kHz

5. The Automatic Input of a Reserve (AIR) in boards of own needs of alternating current

6. Information transfer in industrial control system of substation/power plant under standard protocols:

- ModbusRTU/TCP-

- MACK 60870-5-104-

- MACK OF 61850 (MMS) -

- possibility of sending SMS notifications.

Structure of system:

- industrial freely programmable controller with Linux "MOXA" OS -

- programmable logical TWIDO-controller

- modules of the discrete input "ICP DAS", "Advantech", "MOXA" -

- modules of discrete conclusion "ICP DAS", "Advantech", "MOXA" -

- digital electric Electric device devices -

- modules of an ostsillografirovaniye of the discrete and analog sizes "Beckhoff" -

- the text panel of the operator "Schneider Electric" or the panel computer -

- devices of protection against pulse retension and hindrances of the RS-485 interface.

Features of system:

- the built-in web interface provides information in the form of any screen forms (the table, a symbolic circuit and others) -

- the programmable logic allows to make processing of signals -

- self-diagnostics reveals and signals about malfunction in system of monitoring -

- easy scalability allows to create various systems: from monitoring of one case before monitoring of big boards.
