Description
Technical field
The utility model relates to the sliding shelves of the main transformer shunting switch emergency stop device among a kind of RTU of being integrated in, and belongs to the electrical management monitoring system.
Background technology
The voltage of keeping electric power system changes in allowed limits, safety to the normal operation that ensures electric load and system self is most important, at present, the electric substation of the unmanned or few people on duty of great majority, mainly be to send " remote regulating " order by the dispatcher to carry out remote operation when carrying out voltage-regulation, sliding shelves take place in main transformer shunting switch pressure regulation process often, faults such as stall, as untimely cut-out pressure regulation motor power, " gear is even transferred " will take place cause the voltage severely subnormal, even damage mechanism, burn motor, the safe and stable operation of serious threat electrical network.
Summary of the invention
The purpose of this utility model is to provide the emergency stop device of the sliding shelves of main transformer shunting switch among a kind of RTU of being integrated in, be to guarantee on the existing RTU of the transformer station function basis, rely on PLC at a high speed, powerful logical process ability, the anxious Control Software module of stopping of the sliding retaining of embedded main transformer shunting switch realizes monitoring in real time, anxious the stopping and self check abnormal obliteration function of the sliding retaining of main transformer; RTU receives and assigns the main transformer instruction of " transferring the files ", real time monitoring main transformer gear change and analysis and judgement, when finding " sliding shelves ", suddenly stopping control command cuts off motor power simultaneously to issue gear immediately, prevent that main transformer from causing the voltage severely subnormal because of the motor continuous action in the pressure regulation process, improve power supply quality, prolong service life of equipment, guarantee power grid security, stable, economical operation.
The technical solution of the utility model is achieved in that the sliding shelves of the main transformer shunting switch emergency stop device that is integrated among the RTU, it is characterized in that: at the D20M/g of RTU main frame mainboard is the complete embedded development platform based on the MPC852T of Motorola processor of a cover, MPC852 PowerQUICC is integrated two processing blocks, a processing block is the PowerPC nuclear that embeds, another is communication processing module CPM, the communication processing module is supported seven serial communication passages, two SCC, dual serial Management Controller SMC, a pcmcia interface.
The D20M/g mainboard of described RTU main frame is made up of core board and base plate, core board the is integrated MPC852 of Motorola processor, the FLASH of 32M SDRAM and 16M, Peripheral Interface on the base plate has been expanded the FLASH of 16M, a 10M Ethernet interface, a 100M Ethernet interface, a USB HOST interface, a terminal interface, 8 two line RS-232 serial ports, wherein USB HOST supports mobile storage disc.
Good effect of the present utility model is the 0-5V DC analogue quantity that RTU gathers main transformer electric parameter, switching value state and tap joint position or exported by the gear transmitter, receive and assign the instruction of " transferring the files " of main transformer shunting switch, real time monitoring main transformer gear change process.RTU receives " transferring the files " instruction, carries out data analysis automatically and judges the gear change process, promptly when finding the continuous displacement of YX, judges the sliding shelves of main transformer.In the cycle of transferring the files, the gear no change is judged the main transformer stall.When " sliding shelves ", " stall " fault appearred in main transformer, RTU issues gear immediately, and suddenly stopping control command cut off motor power simultaneously.Send fault, emergent stop signal; On earth whether the RTU device has the self check self-repair function, and the position of main transformer gear is judged in self check,, to pushing up or going beyond the scope the control command of automatic blocking main transformer when self check is unusual, the alert signal of transmitting messages.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described: be integrated in the sliding shelves of the main transformer shunting switch emergency stop device among the RTU, it is characterized in that: at the D20M/g of RTU main frame mainboard is the complete embedded development platform based on the MPC852T of Motorola processor of a cover, MPC852 PowerQUICC is integrated two processing blocks, a processing block is the PowerPC nuclear that embeds, another is communication processing module (CPM, Communications Processor Module), the communication processing module is supported seven serial communication passages, two SCC, dual serial Management Controller (SMC, Serial Management Channels), a PCMCIA(Personal Commputer MemoryCard International Association) interface.The D20M/g mainboard of described RTU main frame is made up of core board and base plate, core board the is integrated MPC852 of Motorola processor, the FLASH of 32M SDRAM and 16M, Peripheral Interface on the base plate has been expanded the FLASH of 16M, a 10M Ethernet interface, a 100M Ethernet interface, a USB HOST interface, a terminal interface, 8 two line RS-232 serial ports, wherein USB HOST supports mobile storage disc.
As shown in Figure 1, the RTU program embeds gear sudden-stop function module, and this program module is monitored the main transformer gear signal in real time, has only gear in effective range, just allows remote control to transfer the files to instruct to issue.Otherwise remote control is selected not return to school, and remote control is carried out and is under an embargo, the operation of transferring the files of this main transformer of locking.Shelves transfer the files " executions " instruct issue after, RTU enters two monitoring periods, first gearshift cycle is called the action phase, following first gearshift cycle is called stationary phase.
First gearshift cycle: be called the action phase, in this time period, gear can only change one grade, when gear change arrives desired value, is considered as this cycle gearshift and finishes, withdraws from this time period, and entering the next gearshift cycle is stationary phase.After this time period finished, gear did not change, and perhaps gear mediates, and was shown as zero, regarded motor rotation blockage as, started anxious stopping immediately.Because RTU does not have to gather the operating voltage and the electric current of the motor of transferring the files, and can't judge whether motor moves, the motionless motor rotation blockage that is considered as without exception of motor.Owing to reasons such as overvoltages, the motor of transferring the files rotation is too fast, during this period gear change more than two grades or two grades, be considered as sliding shelves, start anxious stopping immediately.
The next gearshift cycle: be called stationary phase,, monitor whether gear has change,, start anxious stopping immediately if be considered as sliding shelves when gear change enters this time period after desired value.In this two cycles, the RTU locking instruction of transferring the files.
