Description

Technical field

The invention relates to control and signaling devices used in electrical substations, which, in accordance with the programmed logic, transmit control signals from the dispatcher to substation equipment and signaling data from substation equipment to the dispatch center.

State of the art

The closest in technical essence analogue is the telemechanics device of the controlled point MTK-32.KP (www.systel.ru). The device is a modular hardware and software product. The set and number of modules determine the functions of the device and its information capacity. The device may include data acquisition and transmission modules (processor module); discrete signal input module; input module for current television measurements; interface converter or media converter; telecontrol module; USPD power supply, TS, TIT modules and interface converter.

The disadvantage of this prototype is the lack of reliability associated with the lack of a backup power source.

Utility Model Disclosure

The technical result, the solution of which the proposed utility model is aimed at, is to increase the reliability of the device due to the possibility of working from two power supplies.

The claimed technical result is achieved due to the fact that in a modular telemechanics device, consisting of a processor module, information and field interfaces connected to the processor module, expansion modules 1-16 (telealarm, telecontrol, teleregulation) connected to the processor module, power supply 1 connected to the processor module and expansion modules, an additional power supply 2 is introduced, connected to the processor module and in parallel with the power supply 1 to the expansion modules, the control unit Connected to the processing unit and power supply units, wherein the further control unit connected to an accident power indicator and an alarm unit contacts.

These features are essential with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The essence of the utility model is illustrated in the drawing (see Figure 1).

A modular telemechanics device consists of a processor module, information and field interfaces connected to the processor module, expansion modules 1-16 (remote signaling, telecontrol, teleregulation) connected to the processor module, two power supplies (power supply 1 and power supply 2) connected to processor module and in parallel to expansion modules. The control unit is connected to the processor module and power supplies.

The device operates as follows.

Control commands received via information or field interfaces are received by the processor module, which performs command processing in accordance with predefined algorithms. As a result of processing, the processor module forms a chain of control actions, which is transmitted to the expansion modules in compliance with the sequence and time intervals.

Extension modules, based on the data received from the processor module, change the state of the control relay or generate electrical signals transmitted in the control circuit. Electrical signaling signals transmitted by substation equipment are supplied to expansion modules, where they are converted into signaling data and transmitted to the processor module. The processor module processes the data in accordance with predefined algorithms and transmits the results through information and field interfaces. The power supplies are connected to the control unit, and in the event of a failure of the main power supply unit (power supply unit 1), a signal about its failure arrives at the control unit, and the backup power supply unit (power supply unit 2) is switched on instead of the main one upon the command of the control unit. At the same time, a signal about a malfunction of the main power supply is received from the control unit into the processor module. In this case, the control unit also triggers the alarm contact block and lights up the power failure indicator.
