and 110, sequentially acquiring switch data acquired by a plurality of intelligent power monitoring devices arranged in the transformer substation in a polling mode to obtain a power switch sequence.
Each intelligent power monitoring device corresponds to a power device, each power device is provided with a plurality of power switches, the switch data comprise the numbers and the states of the power switches, and each element in the power switch sequence comprises the numbers and the states.
The electric power system is an electric energy production and consumption system which consists of links such as a power plant, a power transmission and transformation line, a power supply and distribution station, power utilization and the like. The function of the device is to convert the primary energy of the nature into electric energy through a power generation device, and then supply the electric energy to each user through power transmission, power transformation and power distribution. In order to realize the function, the power system is also provided with corresponding information and control systems at each link and different levels, and the production process of the electric energy is measured, regulated, controlled, protected, communicated and scheduled so as to ensure that users obtain safe and high-quality electric energy. The main structures of the power system include a power source (power plants such as hydropower stations, thermal power plants, and nuclear power plants), a substation (a step-up substation, a load center substation, and the like), a power transmission and distribution line, and a load center. The power supply points are also mutually connected to realize the exchange and regulation of electric energy among different regions, thereby improving the safety and the economical efficiency of power supply. The information and control system of the power system is composed of various power devices (detection devices, communication devices, safety protection devices, automatic control devices, monitoring automation systems and dispatching automation systems). The power equipment includes a large number of power switches, and the normal operation of the power equipment is controlled by the on and short circuit states of the power switches. An Intelligent power monitoring Device IED (Intelligent Electronic Device) can be used for monitoring the operating state of the switchgear of the substation. The collection of the state of the power switch can be judged by collecting the on-off condition of the corresponding circuit through the intelligent power monitoring device.
In the embodiment of the present invention, the polling acquisition power switch sequence may be performed at a preset time interval, where the preset time interval refers to a preset time interval, and the time interval may be set manually or determined by parameters of the acquisition device itself. For example, the time interval is manually set according to the specific operation condition of the power equipment, and the time interval for collecting the on-state and the off-state of the power switch each time is determined, and for example, the time interval may be set to 1S, 10S, 1min, and the like. The time interval of the acquisition may also be a time interval of the acquisition according to the sampling rate of the acquisition device itself, and the specific time interval is not limited herein and may be adjusted or set according to actual needs.
In a specific implementation, the switch sequence representing the states of the power switches includes numbers and states of the plurality of power switches, for example, the power switches are numbered, then the states of the plurality of power switches are sequentially collected once or sequentially by the intelligent power monitoring device according to the numbers, the numbers and the collected states are associated and arranged, and then an ordered data set is formed, that is, the switch sequence in the embodiment of the present invention. Next, a specific code can be set in the switching sequence to indicate the on state and the off state, for example, the number "0" indicates the off state, and the number "1" indicates the on state. Alternatively, the on state and the off state may be indicated by other numbers, characters, or the like. The switching sequence of the power switch is mainly used for distinguishing the on-off state of the power switch.

In the embodiment of the invention, the state change of the power switch is monitored, so that the state of the power switch can be continuously collected, and a plurality of groups of switch sequences can be generated according to different collection times. Since the power switch of the power equipment is monitored in real time, the newly acquired first switching sequence can be compared with the second switching sequence acquired at the previous moment to judge whether the state of the current power switch is changed. In other non-real-time monitoring systems, standard data of the reference switch sequences can be set according to needs, or a plurality of groups of reference switch sequences are set according to the working state of the transformer substation, and the corresponding reference switch sequences are selected according to the actual working state during actual judgment.
In a specific implementation, the reference switching sequence is used as a reference to perform data change checking calculation on the power switching sequence, and whether the power switching sequence is changed from the reference switching sequence is determined. Specifically, the adopted check calculation mode can be selected according to actual needs, for example, the two groups of switch sequences are calculated by using a bit exclusive or, a hash value calculation, a subtraction method and the like, and whether the power switch sequence is changed relative to the reference switch sequence is judged. Or matching the corresponding sequence characteristics in the reference switch sequence according to the numbers of the electronic switches in the power switch sequence, and comparing the states of the electronic switches corresponding to the numbers with the corresponding sequence characteristics in the reference switch sequence to determine. The check bits of different power switch sequences can be checked to check whether the power switch sequences are consistent with the reference power switch sequence. The specific check calculation method is many, and is not limited to this, and may be selected according to a specific computing device in an actual implementation.
And step 130, determining the elements of the power switch sequence change as a target set based on the result of the verification calculation.
In the foregoing step 120, a verification calculation is performed on the consistency between the power switch sequence acquired at the current time and the reference switch sequence acquired at the previous time, and in this step, an element that changes from the reference switch sequence acquired at the previous time in the power switch sequence acquired at the current time may be determined according to a result of the verification calculation, so as to determine a target set of data of all changed power switches.
And 140, uploading the target set to the electric power terminal equipment.
In a specific implementation, when the state of the power switch is determined to be changed, the current state information of the power device needs to be uploaded to the power terminal device, so that the power terminal device further determines the state of the power device according to the state information of the power device to make a corresponding response.
According to the technical scheme of the embodiment, the state and the number of the power switch are collected through the intelligent power monitoring device, so that a power switch sequence with the power switch number is obtained, simultaneous monitoring on a plurality of power devices and a plurality of power switches at one time is realized, the collection and the positioning of each power switch can be conveniently realized through the association of the state and the number of the power switch, the specific changed power switch can be determined through the number in the later period, whether the power switch sequence at the current moment is changed compared with the reference switch sequence or not can be effectively determined through checking and calculating the power switch sequence and the reference switch sequence, a target set of changed elements is uploaded to the power terminal device after the state of the power switch of the power device is determined to be changed, and the state determining and calculating of the power switch originally realized by the power terminal device can be transferred to the power switch monitoring device, the calculation amount of the power terminal equipment is effectively reduced, the resource requirement on the power terminal equipment is reduced, the judgment error of the power switch of the power equipment, which is possibly influenced by data errors in the process of transmitting a large amount of data, can be effectively avoided, and the reliability of monitoring the power switch of the power equipment is improved.
Example two
Fig. 2 is a flowchart of a power switch monitoring method according to a second embodiment of the present invention, which is based on the foregoing embodiments and further refines the verification calculation performed on the power switch sequence and the preset reference switch sequence.
The method specifically comprises the following steps:
step 201, sequentially collecting the switching data of the intelligent power monitoring device in a polling manner according to a preset time interval, and obtaining a switching sequence consisting of the number of the power switch and "0" or "1" corresponding to the state of the power switch.
In the embodiment of the invention, the states of the power switch comprise an open state and a closed state, wherein 0 is used for representing the open state, and 1 is used for representing the closed state. The numbers "0" and "1" are only one specific example, and other numbers or letters may be used instead in other embodiments.
In a specific implementation, the power switches of the power equipment may be sorted according to a preset order, each power switch is numbered, then all the power switches are combined with the numbers to perform state acquisition, and then a power switch sequence composed of the numbers and the states with specified lengths is generated. For example, a power plant has 10 power switches, the 10 power switches are numbered in an order of 0-9, then the states of the 10 power switches are obtained at preset time intervals, and a power switch sequence of the form similar to "{ (0,1), (1,0), (2,1), (3,1), (4,0), (5,1), (6,1), (7,1), (8,0), (9,1) }" is generated in the order. Wherein each element corresponds to a power switch.
In one possible embodiment of the invention, the number of the power switches is the serial number of all the power switches of the substation. That is, all the electronic switches of the substation are numbered uniformly to form a uniform code, and then the number is associated with the state of the power switch to form an element of the power switch sequence in the acquisition process, and data errors caused by the change of the acquisition sequence of the power switch or the element sequencing of the power switch sequence can be avoided.
In other embodiments, the number of the power switch may also be a combination of the number of the smart power monitoring device and the number of the power switch under the smart power monitoring device. For example, the intelligent power monitoring device adopts alphabetical sorting, the corresponding power switches under the intelligent power monitoring device adopt numerical sorting, and the numbers are in the forms like "a 1", "a 2", "a 3" … … "an", "b 1", "b 2" … … "bn", and the power switch sequences are "{ (a1,1), (a2,0), (a3,1), (a4,1), (a5,0), (a6,1), (a7,1), (a8,1), (a9,0), (a10,1) }".
Step 202, setting the power switch sequence acquired in the previous acquisition as a reference switch sequence.
In an alternative embodiment of the invention, the power switch sequence obtained last time may be used as a reference switch sequence to determine whether the state of the power switch has changed from the previous acquisition.
In other embodiments, it is also possible to directly set the fixed reference switching sequence. Or different reference switch sequences are set according to different working states of the power equipment of the transformer substation, the power switch sequences are verified, the corresponding reference switch sequences are directly matched according to the working states of the power equipment of the transformer substation, and then specific verification is carried out.
And 203, performing bitwise exclusive-or operation and/or hash operation on the power switch sequence and a preset reference switch sequence.
The exclusive-or operation is a mathematical logic operation mode, and is mainly applied to logic operation. If the two values are not the same, the XOR result is 1. If the two values are the same, the XOR result is 0. The value of the exclusive-or operation is true only if the value of exactly one of the two operands is true and the value of the other one is not.
In the embodiment of the present invention, the bitwise xor operation refers to performing xor operation on values of the same number of bits of the power switch sequence and the reference switch sequence to obtain the first check value. For example, if the power switching sequence and the reference switching sequence are both 10101, the corresponding first check value is 00000; when the reference switching sequence is different from the power switching sequence, for example, the reference switching sequence is 11001, the first check value is 01100, where the second bit and the third bit in the reference switching sequence are different from the power switching sequence, so the value of the second bit and the third bit of the calculated first check value is 1. In addition, when the elements in the power switch sequence are subjected to bitwise exclusive-or operation, the numbers can be matched firstly, namely, the corresponding reference switch sequence elements are determined according to the power switch sequence, so that errors caused by the fact that the sequence of the power switch sequence is inconsistent with the sequence of the reference switch sequence are avoided.
Hash operations (Hash) are the conversion of an input of arbitrary length (also called a pre-mapped pre-image) into a fixed-length output, known as a Hash value, by a hashing algorithm. This transformation is a kind of compression mapping, i.e. the space of hash values is usually much smaller than the space of inputs, different inputs may hash to the same output, so it is not possible to determine a unique input value from a hash value. In short, it is a function of compressing a message of an arbitrary length to a message digest of a certain fixed length. The hash operation may convert a data into a token that is closely related to each byte of the source data.
In this embodiment, a unified hash algorithm is applied to the power switch sequence and the reference switch sequence to perform hash calculation, so as to obtain corresponding hash values, respectively, and the consistency check of the two switch sequences can be realized by comparing whether the two hash values are consistent, that is, whether the power switch sequence is changed relative to the reference switch sequence is determined.
And step 204, determining whether the power switch sequence changes according to the result of the check calculation.
In the foregoing step 203, the consistency between the power switch sequence collected at the present time and the reference switch sequence is checked and calculated, and in this step, whether the power switch sequence is consistent with the reference switch sequence or not can be determined according to the result of the check and calculation, so as to determine whether the state of the power switch is changed or not.
And step 205, when the power switch sequence changes relative to the reference switch sequence, performing bitwise exclusive-or operation to determine an element of the power switch sequence, which changes relative to the reference switch sequence, as a target element.
What is needed in this step is to determine the element in which the power switch sequence changes relative to the reference switch sequence after determining that the power switch sequence changes relative to the reference switch sequence based on the result of the verification calculation. The execution of the bitwise xor operation is only a specific operation manner, and may also be to obtain a changed element based on a result of the check calculation, for example, when the check calculation adopts a bitwise xor operation or a bitwise addition and subtraction method, etc., it may directly determine the changed element, at this time, it is not necessary to separately determine the changed element by the bitwise xor operation, and besides the bitwise xor operation, a bitwise addition and subtraction method, a bitwise hash operation, etc., may also be used for the determination.
Step 206, the set of all target elements is used as a target set.
And step 207, uploading the target set to the electric power terminal equipment.
In a specific implementation, all the power switch sequences are confirmed in the foregoing steps with respect to the element of the reference switch sequence, which changes, that is, the changed power switch in the substation is determined, and then the change information of the power switch needs to be packaged and uploaded. The packing manner may be various, for example, all the target elements mentioned in step 206 are packed into a set, and the set is sent to the power terminal device, or the data of the corresponding intelligent power monitoring device, the power device, or the substation in a period of time is uploaded in a whole packing manner on the basis of the target set. The specific uploaded data content can be changed correspondingly according to actual needs.
