Detailed Description
The present application will be described in further detail with reference to the accompanying drawings.
The embodiment of the application provides a monitoring method based on a DCS (distributed control system), which can be executed by electronic equipment, wherein the electronic equipment can be a server or terminal equipment, and the server can be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server for providing cloud computing service. The terminal device may be, but is not limited to, a smart phone, a tablet computer, a desktop computer, etc.
As shown in fig. 1, a monitoring method based on a DCS system is described as follows (steps S101 to S105):
Step S101, operation data of each area in the DCS are obtained, wherein the operation data comprise data received by a sub-control module of the wind turbine generator.
In this embodiment, during the operation of the wind power plant, distributed control of the wind turbine is generally achieved through a sub-control module in the DCS system, and then operation data of a region corresponding to the wind turbine is obtained through the sub-control module, where the operation data is data collected by the sub-control module through the collecting device, and the operation data includes wind speed, rotational speed of the blade, and power generation current and motor temperature of the wind turbine.
Further, before acquiring the operation data of each region in the DCS system, the method further includes: acquiring regional distribution information of a wind power plant; dividing the area of the wind power plant based on the area distribution information to obtain a plurality of monitoring areas; carrying out importance level division on the monitoring area to obtain a division result; acquiring logic functions of sub-control modules of the DCS of each monitoring area based on the dividing result; and carrying out area packing on the monitoring area based on the logic function of the sub-control module to obtain a packing area.
In this embodiment, before the operation data of each region in the DCS system is obtained, each region of the wind power plant needs to be divided, different regions are packed and sorted, so as to obtain a plurality of packed regions, that is, the plurality of regions are combined, and the sub-control modules of the DCS system are monitored through the packed regions.
In a wind power plant, different functional areas such as a transmission area, a power generation area, a storage area and a power transformation area are present, wherein the areas are set as monitoring areas, each monitoring area comprises a plurality of sub-control modules of a DCS system, and logic functions of the plurality of sub-control modules of each monitoring area have a certain logic relationship; taking a power generation area as an example, the power generation area comprises control of a wind turbine generator, control of current conversion, control of a power supply, collection of a current signal and control of power generation capacity; because a plurality of sub-control modules are needed to be matched in each functional area to realize final logic control, the packaging area can be set to be a monitoring area according to the logic functions of the sub-control modules, the monitoring of all the sub-control modules in the packaging area can be realized conveniently by monitoring the logic functions of one sub-control module, so that the waste of monitoring resources is reduced, and the DCS can be monitored more conveniently.
Further, performing importance level division on the monitoring area, and obtaining a division result includes: acquiring a corresponding functional area in a monitoring area, wherein the functional area comprises a power generation area, a power transformation area, a storage area and a transmission area; acquiring the influence degree of each preset influence factor on the functional area, wherein the influence degree comprises the influenced coefficient of each preset influence factor on the functional area; determining an importance level of each functional area based on the influence degree; and dividing the functional areas according to the importance level to obtain a division result.
In this embodiment, when dividing the importance level of the monitoring area, when setting the influence factor, the importance level of each functional area needs to be determined according to the influence degree received by each functional area, for example, the influence factor includes temperature, weather, operation time, wind speed, and the like, and the influence of temperature on the storage unit and the transmission unit is large because the influence of temperature on the current and the electronic activity is large, where the influence of too low temperature on the storage unit is large and the influence of too high temperature on the transmission unit is large, and at this time, the importance level may be defined according to the time when the detected temperature value is not within the preset threshold range.
For example, in north China, the annual high-temperature weather is june to october, and the annual low-temperature weather is october to january, so that the importance level of the transmission area is highest, the importance level of the storage area is second, the importance level of the other functional areas is third, with respect to the influence factor of temperature.
In this embodiment, according to the change degree of each influence factor, the influence degree of each influence factor on the functional area is different, and a large amount of data needs to be collected at this time to establish an influence factor database, so that the importance level of each functional area is more conveniently determined.
For each influencing factor, determining the importance level of each functional area, then after determining all the importance levels according to the influence degree, integrating to finally determine the final importance level of the functional area, and taking the final importance level as a division result.
For example, the temperature is determined as the first importance level of the transmission area, but the importance level of the transmission area is the third importance level among the remaining influence factors, so the final importance level of the transmission area is the third importance level.
That is, the final importance level is determined as the importance level ratio of the functional area in each influence factor, and in particular, when the importance level of one functional area after the four influence factors are respectively judged is respectively the second importance level, the third importance level and the third importance level, the final importance level of the current functional area is judged to be the second importance level at this time.
Step S102, data association is carried out based on the operation data of all the areas, and an association result is obtained.
Specifically, performing data association based on the operation data of all the areas, and obtaining association results includes: performing area association on the monitoring area based on the logic function of the sub-control module to obtain an association area, wherein the association area comprises monitoring areas with the logic functions of the sub-control module mutually affected; basic information of all sub-control modules in the associated area is acquired; and carrying out data association on the operation data based on the basic information and the association area to obtain an association result.
In this embodiment, after the monitoring areas are divided, the areas are associated with each other to obtain associated areas, for example, a power generation area, a transmission area and a storage area, and the three areas are mutually associated areas, so that data association is required according to operation data of the associated areas at this time to obtain corresponding association results, and operation data corresponding to all sub-control modules in the associated areas can be obtained through operation data of one sub-control module by using the association results, so that monitoring of all control modules of the DCS system is more convenient.
And step S103, performing front-end monitoring on the DCS based on the association result to obtain a front-end monitoring result.
Specifically, performing front-end monitoring on the DCS based on the association result, and obtaining the front-end monitoring result includes: judging whether the operation data is consistent with preset operation data or not based on the association result; if the operation data is inconsistent with the preset operation data, determining abnormal information based on the operation data; determining the affected proportion of all areas based on the abnormal information and the association result; sequencing the affected proportion according to a preset rule to obtain a sequencing result; determining future abnormal data of the area based on the sorting result and the abnormal information; and taking the future abnormal data as a front monitoring result.
In this embodiment, after each region is associated to obtain an association result, each sub-control module of the DCS system is monitored according to the association result, when the operation data detected by one sub-control module in the associated region is inconsistent with the preset operation data, the abnormal information is determined according to the operation data, the affected proportion of the corresponding region is determined according to the abnormal information and the association result, then the future abnormal data of the associated region is determined according to the affected proportion, and when the future abnormal data occurs, the future abnormal data is used as the pre-monitor result.
For example, in a wind power generation field, the generated current at the moment is determined according to the acquired wind speed, but the generated current at the moment has an error with the preset generated current, and when the generated current is abnormal, the generated current has the most serious influence on a power transformation area, so that the power transformation area is most seriously influenced, and the influenced proportion is the largest; the influence of the generated current on the transmission region is minimal, and the affected ratio is minimal because the transmission region can be transmitted without exceeding the upper limit value regardless of the generated current.
After determining the affected proportion of the abnormal information to the association result, sequencing the affected proportion according to a preset rule, wherein the preset rule can be from big to small or from small to big; after the sequencing result is obtained, future abnormal data of each associated area are calculated according to the sequencing result and the abnormal information, so that front monitoring of the DCS is realized.
Step S104, judging whether the DCS system fails or not based on the front-end monitoring result, and if so, turning to step S105.
Specifically, judging whether the DCS system fails based on the front-end monitoring result includes: setting a preset association threshold according to the association result; calculating a current association value based on the pre-monitoring result; judging whether the current association value is larger than a preset association threshold value or not; if the current association value is larger than the preset association threshold value, judging that the DCS system fails.
In this embodiment, when it is required to determine whether a fault occurs according to the pre-monitoring result, a current association value needs to be calculated according to the pre-monitoring result, for example, when the pre-monitoring result includes that the abnormal information is abnormal in the generated current and the temperature of the transmission area is abnormal, the current association value is calculated through the affected proportion, that is, the affected proportion is arranged from large to small to be 5,3 and 1, different affected proportions are determined through different abnormal information calculations, then the affected proportions are subjected to addition calculation to obtain a final affected proportion, that is, the current association value, then whether the current association value is greater than the preset association value is determined, when the current association value is greater than the preset association value, the fault in the association area can be determined, and then the DCS system at the moment is determined to have the fault; when the current association value is not greater than the preset association threshold, the abnormal information does not affect other association areas or does not appear, and the DCS system operates normally.
Further, after judging whether the DCS system has a fault based on the pre-monitoring result, the method further comprises: acquiring all first fault information of the DCS based on the big data; establishing a fault information database based on the first fault information; if the DCS system is judged to have faults based on the front monitoring result, second fault information is obtained; judging whether first fault information corresponding to the second fault information exists in the fault information database; if the first fault information corresponding to the second fault information does not exist in the fault information database; and adding the second fault information into the fault information database to obtain a new fault information database.
In this embodiment, after determining that a DCS system fails, it is necessary to search all first failure information of the DCS system using big data, then establish a failure information database according to the first failure information, then obtain second failure information through a failure of the current DCS system, search from the failure information database, determine whether there is first failure information identical to the second failure information in the failure information database, and when there is no first failure information identical to the second failure information in the failure information database, supplement the second failure information to the failure information database to obtain a new failure information database; when first fault information which is the same as second fault information exists in the fault information database, the first fault information is pushed to staff according to a preset processing strategy stored in the fault information database, and then the staff overhauls, so that the method is more convenient.
And step S105, controlling the DCS system to perform early warning.
In the embodiment, when the related area in the DCS system fails, the DCS system is controlled to send out alarm information, so that a worker can monitor the DCS system in time, the DCS system is protected and maintained rapidly, and the influence of the DCS system on the wind power plant is reduced.
