Description
Technical Field
The invention relates to a transformer substation switching operation automatic detection technology, in particular to a transformer substation operation information identification and confirmation system.
Background
When a substation performs equipment switching operation (pulling and closing a circuit breaker and a disconnecting switch), the operation regulations require that position change information of equipment is observed not only on an equipment body (primary equipment switching-off and switching-on indication) but also on a monitoring background (secondary equipment switching-off and switching-on indication), and when the position change of the equipment and the position change of the equipment are synchronous, the successful operation of the equipment can be confirmed.
In order to strictly execute the operation procedures, when each operation team of the power transformation operation and maintenance room performs switching operation, generally 3 persons are configured for each group to perform the switching operation simultaneously, wherein 2 persons perform field operation, 1 person observes monitoring background information in a main control room, and telephone communication equipment operation information is between field operation personnel and monitoring background personnel. When the operators are insufficient, 2 persons are generally configured for operation in each group, after the operators perform field device operation, the operators return to the main control room to observe the change information of the monitoring background, if the information on the two sides does not correspond (the first device opening and closing indication is displaced successfully, and the second device opening and closing indication is not displaced), the operators return to the field to perform repeated operation, and the operation is repeated in such a way until the device operation is successful or the device failure is judged, the next operation is performed, and in the observation process, the situation that the position change is performed synchronously is difficult to observe, and complicated timing operation is required.
From the above practical situation, the personnel use efficiency of the 3-person group mode is not high (about 50% of waste), the working efficiency of the 2-person group mode is very low, the time between the operation site and the master control room is at least 5 times longer than the operation time (the time is possibly longer according to the scale of the transformer substation and the size of the site), the transformer substation of the power supply company with the continuously open sun in the state has been realized without people, the personnel fixing standard of the operators is changed, and each operator is invaluable.
Disclosure of Invention
The invention aims to provide a substation operation information identification and confirmation system, which converts actions on an equipment body into digital signals (primary equipment switching-off and switching-on instructions) by utilizing a synchronous data transmission mode, simultaneously obtains the digital signals (secondary equipment switching-off and switching-on instructions) on a monitoring background, and synchronously transmits the digital signals to one equipment for identification and judgment so as to solve the problem of complex operation of traditional multi-user cooperation.
The invention is realized by the following technical scheme:
the substation operation information identification and confirmation system comprises a secondary circuit formed between an auxiliary switch of an operated device and a monitoring background, and is characterized by also comprising a field information extraction device, a background information extraction device and a mobile terminal, wherein,
the field information extraction device: the device is used for acquiring device field operation information A at the field position of the operated device, encoding the device field operation information A and then sending the encoded device field operation information A to the mobile terminal;
background information extraction means: the system comprises a monitoring background, a mobile terminal and a monitoring server, wherein the monitoring background is used for acquiring equipment field operation information B in the monitoring background, encoding the equipment field operation information B and then sending the encoded equipment field operation information B to the mobile terminal;
a mobile terminal: the device is used for receiving the device field operation information A and the device field operation information B after the device is subjected to position change when the operated device is operated, comparing the device field operation information A with the device field operation information B, and outputting the comparison result.
Through detailed investigation and design, the invention provides a substation operation information identification and confirmation device, and the waste and low efficiency phenomena can be completely eliminated.
The principle of the method is as follows:
the field information extraction device: at the field position of the operated equipment, the field operation information (the switch-on/off position variation of the primary equipment) of the equipment is taken out in a photoelectric isolation mode, and then is correspondingly coded and sent out in a wireless (WIFI, RF, FM and the like) signal or wired mode; meanwhile, information (secondary equipment switching-off and switching-on position variation) of a monitoring background is also sent out in a wireless (WIFI and the like) signal or wired mode; when the position of the equipment is changed, the two groups of coded signals are simultaneously and automatically transmitted to a mobile terminal carried by an operator, the terminal compares the two groups of information, confirms the success of the operation after judging the correctness, and outputs a result (automatically informs the operator by voice and screen display). After the operation, the operator can obtain two groups of confirmation information required by the operation procedure on site without going to and going from the main control room or contacting with the main control room, and can immediately complete the operation confirmation step to perform the next operation task.
The substation operation information identification and confirmation device further has the function of primary judgment of secondary circuit faults: when the field primary equipment is operated in place (confirmed by information such as primary equipment position indication, operation mechanism displacement, equipment operation connecting rod displacement and the like), but the mobile terminal does not receive the comparison task information or the information sent by the monitoring background (repeated operation can be carried out again, and the situation still exists), the fault of a secondary circuit between the auxiliary switch of the operated equipment and the monitoring background can be preliminarily explained.
As the auxiliary switch is an element of the primary equipment, the field operation information A of the system equipment can be an auxiliary node of the system equipment, and the change condition of the auxiliary node is consistent with the position change of the primary equipment and can be regarded as the field operation information A of the equipment. Similarly, in the existing monitoring secondary loop, the change condition of the auxiliary node can be detected as the position change of the primary equipment. Therefore, preferably, the device field operation information a is signal change information at an auxiliary node of an auxiliary switch. Preferably, the field operation information B of the device is obtained through a secondary loop formed between an auxiliary switch of the operated device and the monitoring background.
Wherein, concretely: the field information extraction device comprises an equipment position change information extraction module and a first transmission module, wherein the equipment position change information extraction module comprises: the system comprises a leading-out port for leading out a node signal of an auxiliary switch, a photoelectric isolation loop connected with the leading-out port, and a signal conversion coding loop connected with the photoelectric isolation loop; the photoelectric isolation loop isolates the input signal (strong current) of the auxiliary switch of the equipment from the module (weak current), ensures that the module does not influence the relevant devices of the transformer substation, and simultaneously meets the interface requirement of the module. The first transmitting module is connected with the conversion coding loop, and the first transmitting module is connected with the mobile terminal receiving module in a quantity transmission mode. The conversion coding is used for coding the signal input by the auxiliary switch through photoelectric isolation according to a specified format and then sending the coded signal to the first transmitting module.
To prevent duplication of device information, the encoder encodes using the following format:
device unit name + substation name + device number + position variation
The device unit name, the substation name and the device number are required to be provided with unique corresponding coding libraries; there are only 2 cases of position variation: mother I and mother II. The first transmitting module transmits the information sent by the signal coding loop in a wireless signal mode. When no information is sent by the coding loop, the loop is in a dormant state, and when the information arrives, the loop is started immediately and repeatedly transmits the information for about 1 s. The device can be transmitted in a WIFI, GPRS, radio frequency, 2G or 4G, Bluetooth and other mobile phone signal modes, and the transmission distance covers the equipment field of the whole transformer substation.
Preferably, the background information extraction device comprises an extraction device and a second transmission module which are connected with the background monitor, the extraction device connected with the background monitor is connected with the second transmission module, the extraction device connected with the background monitor is connected with the database of the background monitor, and the extraction device connected with the background monitor directly extracts the equipment field operation information B which comes from the background monitor, is confirmed to be correct and is coded. The device field operation information B, namely the background monitoring position change signal is the information from the protection background and confirmed, is the correct information of the device position change in the protection background, and is directly taken from the signal of the background monitoring microcomputer. The transmitting module of the background information extracting device sends out the equipment position change signal directly taken from the background monitoring microcomputer in a wireless signal mode. When no information of the device position change signal exists, the loop is in a dormant state, and when the information arrives, the loop is started immediately and repeatedly transmits the information for about 1 s. The device can be transmitted in a WIFI, GPRS, RF, 2G or 4G, Bluetooth and other mobile phone signal modes, and the transmission distance covers the equipment field of the whole transformer substation.
The mobile terminal (the module adopts CPU as core and develops special APP to operate system) includes:
device location information receiving circuit: for receiving the field operation information a of the device,
monitoring information receiving circuit: for receiving the field operation information B of the device,
a device location decoding identification unit: a corresponding connecting device position information receiving circuit for decoding and identifying the field operation information A of the device,

and (3) judging a loop: the device is used for comparing whether the decoded and identified device field operation information A is consistent with the device field operation information B or not;
and the comparison result feedback unit is used for feeding back the comparison result.
The frequency of the equipment position information receiving loop is different from that of the monitoring information receiving loop. The two receiving loops have different frequencies and respectively correspond to the equipment position change information extraction and transmission module and the background monitoring information transmission module, and are always in a receiving state after the handheld terminal module is started, so that the two receiving loops are not interfered with each other.
The equipment position decoding and identifying unit and the monitoring decoding and identifying unit are both composed of a decoding loop and an identifying loop, wherein the decoding loop decodes information sent by the corresponding receiving loop, the decoding format of the decoding loop is inverse operation with the corresponding coding loop format, and the decoding information is sent to the corresponding identifying loop. The identification loop is used for judging the information sent by the decoding loop, confirming the correctness of the information, discarding the frame information if the judgment result is no, and sending the information to the output loop if the judgment result is true.
The judgment loop is used for carrying out logic analysis and comparison on the two paths of information and sending a comparison result to the output loop. The loop is realized by adopting a mature CPU chip on the market, and a special APP is developed to carry out control such as operation, logic, setting and the like.
The comparison result feedback unit is regarded as an output loop, and can generally adopt two parts of voice output and display output.
The two output formats of the equipment field operation information A and the equipment field operation information B are consistent, the output time is consistent, and only the output modes are different. The output format is as follows:
power supply, isolating switch and switch
Displacement time: and (c) a second.
When the mobile terminal compares the device field operation information a with the device field operation information B,
when the comparison result of the equipment field operation information A and the equipment field operation information B is synchronous and consistent, the mobile terminal outputs equipment operation success information;
when the comparison result of the equipment field operation information A and the equipment field operation information B is asynchronous or/inconsistent, the mobile terminal outputs equipment operation unsuccessful information;
