MODULE CONTROL AND MONITORING CELL Switchgear amp; Digital Substation With Cell of the complex distribution device provided with such MODULE

摘要

The invention relates to the field of electric power and can be used when creating new and upgrading existing electrical substations in accordance with the concept of digital substation. Technical result of utility model - improved performance of digital processing and reliability of switchgear unit with control. its coupling with other intelligent electronic devices of a substation digital interface unified in accordance with IEC 61850 international standard module comprises a first controller (1), the second controller (2) and the third controller (3). The controller (1) is provided with analog inputs (4) and digital inputs (5) for connection to the corresponding outputs of the sensors cell state (6) CRU. The controller (2) is provided with a serial port (7) connected to the touch screen (8). The controller (3) provided with digital inputs (9) for connection to the sensors status cell (6), and digital outputs (10), which is connected to the generator (11) cell relay control signals (6). Controllers (1), (2) and (3) are connected by an internal LAN (12). Controllers (2) and (3) are provided with ports duplicate Ethernet: the controller (2) - first redundant port (13) and the controller (3) - second redundant port (14). The substation comprises a cell (6) switchgear provided with the proposed modules (17) and digital sensors (18) voltage and current of the main circuit switchgear, a first LAN Ethernet with redundant buses (15) and a second Ethernet LAN with redundant buses (16), and complex (19) and a complex control system (20) RPA. Complexes (19) and (20) are provided with modules (21) interfacing with duplicate Ethernet buses. Using modules (21) to the busbars (15) are connected complex (19) and a set (20) and the tires (16) - a complex (20). By tire (16) is also connected to the outputs of sensors (18). Modules (17) of cells (6) connected to ports (13) and (14) to the redundant buses (15) and (16) respectively. 2 n.p.f. 2 yl.
