Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
As described in the background art, the existing remote centralized control system for the photovoltaic power station has the problems that important alarm information is buried in alarm information which does not need to be processed, the important alarm information is difficult to identify, a corresponding processing mode cannot be provided for special alarm information, and the problem that workers can not analyze the problems of the photovoltaic power station according to different historical alarm information is solved. The inventors have found that the cause of the problem is as follows.
The main processing methods of the existing photovoltaic power station remote centralized control system for numerous alarm information in the system include the following three methods:
and (one) no treatment is carried out. Once the system collects the alarm information, the alarm information is displayed to a centralized control system user if the alarm page is not closed, the user needs to find the alarm needing to be processed in the massive alarm information, then the order dispatching operation is carried out on the offline operation and maintenance personnel, the alarm which is considered not to be processed is manually closed, and the processed alarm information of different types is displayed in a centralized mode on the closed alarm page. This approach has the following disadvantages: 1. because the number of photovoltaic power stations managed by the system is large, and the number of intelligent devices generating alarm information in the power stations is large, if no processing is performed, the large number of alarm information is directly presented to a user, and the alarm information which really needs to be processed urgently can be submerged in the alarm which does not need to be processed and is difficult to identify; 2. the system only provides the closing and dispatching operation functions aiming at the alarm information, and in the actual operation, the inventor finds that some alarm information has the possibility of automatic recovery, and the processing mode can not carry out special processing aiming at the situation, so that the alarm information is submerged by the newly generated alarm information and is difficult to find out; 3. the processed different types of alarm information are all displayed in a centralized manner on the closed alarm page and cannot be checked in a classified manner.
And (II) carrying out grading processing on the acquired alarm information by the system. For example, all the alarm information is divided into four categories, namely fault, alarm, prompt and suggestion, a user can select one or more of the four categories to view in a classified manner, further find the alarm needing to be processed in the various categories of alarm information, carry out the operation of dispatching orders to the offline operation and maintenance personnel, manually close the alarm which is considered not to be processed, and intensively display the processed alarm information of different types on a closed alarm page. This approach has the following disadvantages: 1. because the number of photovoltaic power stations managed by the system is large, and the number of intelligent devices generating alarm information in the power stations is large, even if the alarm information is classified and displayed, the number of the alarm information is still huge, so that the alarm information which really needs to be processed urgently can be submerged in the alarm which does not need to be processed and is difficult to identify. For example, 1881960 total alarms (including faults, alarms, prompts and suggestions) are turned off by a certain photovoltaic power station centralized control system from 1/2020 to 1/11/2020, and only 17417 alarms in the faults are checked; 2. the processed different types of alarm information are all displayed in a centralized manner on the closed alarm page and cannot be checked in a classified manner.
And (III) the system provides an alarm information shielding function, any alarm information can be shielded, and after shielding setting is carried out, the system does not show the alarm to the user any more in a 'one-off' mode. The user can find the information needing to be processed in the rest alarm information, the order dispatching operation is carried out on the offline operation and maintenance personnel, the alarm which is considered not to be processed is manually closed, and the processed alarm information of different types is all displayed in a centralized mode on the closed alarm page. This approach has the following disadvantages: 1. because the number of photovoltaic power stations managed by the system is large, the environment and the used equipment of each photovoltaic power station are different, the alarm information is simply not displayed to a user through the alarm information shielding function, and the real operation condition of the power station cannot be displayed to the user; 2. the processed different types of alarm information are all displayed in a centralized manner on the closed alarm page and cannot be checked in a classified manner.
In order to solve the above problems, an embodiment of the present invention provides a photovoltaic power station monitoring method. Fig. 1 is a schematic flow chart of a monitoring method for a photovoltaic power station according to an embodiment of the present invention. The method can be applied to the situation of processing the alarm information generated by the photovoltaic power station equipment managed by the photovoltaic power station remote centralized control system, and can be executed by the photovoltaic power station monitoring system provided by the embodiment of the invention. As shown in fig. 1, the photovoltaic power station monitoring method specifically includes the following steps:
and S110, acquiring monitoring information of the photovoltaic power station equipment.
The monitoring information comprises warning information of the photovoltaic power station equipment. Specifically, the photovoltaic power station monitoring system can manage a plurality of photovoltaic power stations simultaneously, can monitor photovoltaic power station equipment in real time, and acquire monitoring information of each equipment. The photovoltaic power station equipment comprises photovoltaic inverters, a combiner box, an environment detector, a communication device, an ammeter, line protection equipment, a transformer, a temperature and humidity sensor, a string, an alternating current power distribution cabinet, acquisition equipment, bus protection equipment, Static Var Generators (SVG) and other equipment in the photovoltaic power station. The monitoring information of the photovoltaic power station equipment comprises alarm information, and the photovoltaic power station equipment can generate various alarm information such as prompts, faults, suggestions and the like, for example, equipment startup and shutdown alarm information, equipment fault alarm information, equipment startup suggestion alarm information and the like.
And S120, screening alarm information needing manual processing in the monitoring information of the photovoltaic power station equipment.
Specifically, the warning information generated by various photovoltaic power station equipment can be acquired through a photovoltaic power station monitoring system, and the system can be used for carrying out pre-judgment according to experience or preset rules, screening out the warning information needing manual processing and displaying the warning information to a user, so that unimportant warning information can be automatically filtered, and the warning information really needing processing urgently can be displayed to the user. Optionally, the warning information which is judged by the system to be unnecessary to be manually processed can be separately stored in one area or page for the user to analyze and view, so that the user can know the real and comprehensive operation condition of the photovoltaic power station equipment.
And S130, isolating the alarm information meeting the preset conditions and needing manual processing.
Wherein, the alarm information meeting the preset condition is the alarm information which can not be processed by the user. Specifically, the user can check the alarm information which is automatically screened out by the system and needs to be manually processed, and judge whether the alarm information needs to be distributed to a work order, so that operation and maintenance personnel can carry out processing on the scene according to the alarm condition of the photovoltaic power station equipment. Because some alarm conditions of the photovoltaic power station equipment have the possibility of automatically recovering the normal state, if the alarm information can be automatically recovered, the work order does not need to be dispatched for processing. The user cannot determine whether and when certain alarm information can be automatically recovered, and therefore cannot determine the type of alarm information, i.e., the processing manner of the alarm information satisfying the preset condition, temporarily. The system can perform isolation operation on the alarm information which is judged by the user to meet the preset condition, and suspend or delay processing of the alarm information according to the state of the alarm information.
S140, determining the operation and maintenance mode of the photovoltaic power station equipment corresponding to the alarm information according to whether the alarm information meeting the preset condition can be automatically recovered within the set time.
The isolated alarm information can be processed differently according to whether the alarm information meeting the preset condition can be automatically recovered within the set time. For example, if the alarm information meeting the preset condition can be automatically recovered within the set time, the alarm information does not need to be continuously processed manually; if the alarm information meeting the preset condition cannot be automatically recovered within the set time, the work order can be dispatched so that operation and maintenance personnel can go to the site for processing. After the warning information meeting the preset condition is isolated and observed for a period of time, different processing modes are selected according to the current state of the warning information, so that the waste of manpower and material resources caused by dispatching the worksheet after the warning information is received at the beginning can be avoided, the misjudgment of neglecting the warning condition under the condition that the warning information processing mode is not determined by a user can be prevented, and the occurrence of equipment accidents of the photovoltaic power station is prevented.
According to the technical scheme of the embodiment of the invention, the photovoltaic power station equipment can be monitored, the warning information needing manual processing is automatically screened from the massive monitoring information through the system for being checked by a user, the warning information which is judged by the user to meet the preset condition is isolated, and the operation and maintenance mode of the photovoltaic power station equipment is determined according to whether the warning information meeting the preset condition can be automatically recovered within the set time. The technical scheme of this embodiment, it is difficult to discernment to have alleviated important warning information among the current photovoltaic power plant monitored control system, and can't provide the problem of corresponding processing mode to special warning information, can monitor photovoltaic power plant equipment automatically, the work load of fortune dimension personnel has been alleviateed, the processing time of monitoring information has been shortened, the fortune dimension efficiency of photovoltaic power plant equipment has been promoted, important warning information has been avoided submerging in magnanimity monitoring information, provide the isolation operation for the warning information that the user can't confirm the processing mode, special circumstances special treatment, with the actual fortune dimension demand of confirming photovoltaic power plant equipment, the accuracy of the work of dispatching an order and fortune dimension has been improved
Fig. 2 is a schematic flow chart of another photovoltaic power plant monitoring method according to an embodiment of the present invention. On the basis of the technical scheme, the method for screening the alarm information needing manual processing from the alarm information of the photovoltaic power station equipment is further optimized. Optionally, the alarm information needing to be processed manually is alarm information needing to be processed by operation and maintenance personnel going to the field, or alarm information needing to be further analyzed by a user. Correspondingly, as shown in fig. 2, the photovoltaic power station monitoring method specifically includes:
s210, acquiring monitoring information of the photovoltaic power station equipment.
S220, judging whether the monitoring information of the photovoltaic power station equipment contains alarm information which needs operation and maintenance personnel to go to the site for processing or needs further analysis of a user.
Specifically, the photovoltaic power station monitoring system can automatically filter unimportant alarm information and display the alarm information needing manual processing to a user, wherein the alarm information needing manual processing is generally the alarm information which is judged by the system according to experience or preset rules and needs to be processed by operation and maintenance personnel on site, or the alarm information needing further analysis by the user to determine a processing mode.
And S230, if the photovoltaic power station equipment monitoring information contains warning information which needs operation and maintenance personnel to go to the site for processing or needs further analysis of a user, displaying the warning information to the user.
Specifically, if the system determines that the current alarm information needs the operation and maintenance personnel to go to the field for processing, or needs the user to further analyze, the system displays the alarm information to the user, so that the user can judge according to the actual situation of the alarm information, determine to distribute a work order to enable the operation and maintenance personnel to go to the field for processing, or further analyze and then determine the specific processing mode of the alarm information.
And S240, isolating the alarm information meeting the preset conditions and needing manual processing.
And S250, determining the operation and maintenance mode of the photovoltaic power station equipment corresponding to the alarm information according to whether the alarm information meeting the preset condition can be automatically recovered within the set time.
Optionally, the photovoltaic power plant monitoring method further includes: storing alarm information which does not need operation and maintenance personnel to go to a field for processing or alarm information which does not need further analysis of a user to an alarm area which does not need processing; and storing the alarm information needing to be processed by the operation and maintenance personnel on site or the alarm information needing to be further analyzed by the user into an alarm area to be processed. In particular, the photovoltaic power plant monitoring system may comprise different categories of alert information storage areas or pages, such as no-process alert zones and pending alert zones. If the system judges that the current alarm information needs the operation and maintenance personnel to go to the site for processing or needs the further analysis of the user, the alarm information can be stored in the alarm area to be processed, and the user can directly check the alarm information of the alarm area to be processed after the system is screened, so that the alarm quantity processed by the operation and maintenance personnel can be greatly reduced, the processing time of the alarm information is greatly shortened, and the operation and maintenance efficiency is improved. If the system judges that the current alarm information does not need operation and maintenance personnel to go to the site for processing or further analysis of the user is not needed, the alarm information can be stored in an alarm area which does not need processing, even if the system filters the alarm information, the user can still know the real condition of the operation of the photovoltaic power station equipment through the alarm area which does not need processing, and the operation and maintenance analysis of the photovoltaic power station equipment is facilitated.
Fig. 3 is a schematic flow chart of another photovoltaic power plant monitoring method according to an embodiment of the present invention. On the basis of the technical scheme, the monitoring method of the photovoltaic power station is further optimized. As shown in fig. 3, the photovoltaic power station monitoring method specifically includes:
s310, acquiring monitoring information of the photovoltaic power station equipment.
Optionally, the monitoring information further comprises operational data of the photovoltaic power plant device. Specifically, the monitoring information includes alarm information and operating data of the photovoltaic power plant equipment. The warning information of the photovoltaic power station equipment and the operation data of the equipment corresponding to the warning information, such as historical operation data and real-time operation data of certain equipment, can be acquired through the photovoltaic power station monitoring system.
And S320, judging whether the alarm information needs to be processed by operation and maintenance personnel on site or not or needs to be further analyzed by a user according to the judgment rules in the alarm judgment rule base and by combining the alarm information and the operation data.
Specifically, the photovoltaic power station monitoring system may include an alarm judgment rule base, and the judgment rule in the alarm judgment rule base may be to judge the type of the alarm information according to experience, for example, judge the processing mode of the type of the alarm information by the user in the historical alarm information, and if the user performs the order dispatching processing on the type of the alarm information, the system may automatically screen the alarm information as the information that the operation and maintenance personnel need to go to the site for processing. The judgment rule may also be a judgment rule according to a designated priority principle, for example, the priority principle includes that fault alarm information is processed preferentially, the system may screen the fault alarm information as information that needs the operation and maintenance personnel to go to the field for processing, and screen the prompt type and the suggestion type alarm information as information that does not need the operation and maintenance personnel to go to the field for processing or does not need the user to further analyze. The system can combine one or more of the judgment rules, make judgment according to historical operation data and real-time operation data of the equipment corresponding to the alarm information, and combine the actual state of the equipment on the basis of following the judgment rules so as to make more accurate judgment and screening.
S330, self-adaptive adjustment is carried out on the judgment rules in the alarm judgment rule base.
Illustratively, the alarm judgment rule base has a self-adaptive adjustment function, and can perform repeated analysis judgment and self-learning, for example, the accuracy of the judgment rule is determined by combining the automatic judgment result of a system on certain types of alarm information and the judgment result of further analysis by a user, so that the judgment rule can be continuously perfected, the accuracy of analysis judgment on various types of alarm information is improved, and the improvement of the operation and maintenance efficiency of the photovoltaic power station is facilitated.
And S340, if the photovoltaic power station equipment monitoring information contains warning information which needs operation and maintenance personnel to go to the site for processing or needs further analysis of a user, displaying the warning information to the user.
And S350, performing isolation operation on the alarm information meeting the preset conditions and needing manual processing.
And S360, determining the operation and maintenance mode of the photovoltaic power station equipment corresponding to the alarm information according to whether the alarm information meeting the preset condition can be automatically recovered within the set time.
Fig. 4 is a schematic flow chart of another photovoltaic power plant monitoring method according to an embodiment of the present invention. On the basis of the technical scheme, the monitoring method of the photovoltaic power station is further optimized. Optionally, the alarm information that needs to be manually processed includes alarm information that the user determines that the order needs to be dispatched and alarm information that does not need to be dispatched.
Correspondingly, as shown in fig. 4, the photovoltaic power station monitoring method specifically includes:
and S410, acquiring monitoring information of the photovoltaic power station equipment.
And S420, screening alarm information needing manual processing in the monitoring information of the photovoltaic power station equipment.
And S430, performing order dispatching operation on the alarm information to be subjected to order dispatching processing, so that operation and maintenance personnel go to the site to perform operation and maintenance on the photovoltaic power station equipment, and storing the alarm information to be subjected to order dispatching processing to an order dispatching alarm area.
Specifically, the alarm information that needs to be manually processed can be divided into alarm information that needs to be dispatched and alarm information that does not need to be dispatched. The alarm information to be dispatched can be fault alarm information, for example, when the alarm information trips the SVG device, the alarm information is the alarm information to be dispatched and processed, and operation and maintenance personnel are required to go to the site for processing. The alarm information not requiring the dispatching process may be alarm information of a prompt class or a suggestion class, for example, when the alarm information is the power-on or power-off of the transformer equipment, the alarm information is the alarm information not requiring the dispatching process. The user can judge the alarm information which is automatically screened by the system and needs to be manually processed, and determine whether the current alarm information is the alarm information which needs to be processed by the order dispatching. The system can obtain the judgment result of the user, and performs the dispatching operation on the alarm information which is judged by the user to be required to be dispatched, so that the operation and maintenance personnel can go to the site to maintain the corresponding equipment, and the alarm information which is required to be dispatched and processed is stored in the dispatching work order alarm area.
S440, displaying the alarm information which does not need to be subjected to the order dispatching processing to the user so as to determine whether the alarm information meets the preset condition.
For example, the alarm information that does not need to be processed by dispatching may be alarm information of a prompt class or a suggestion class, or alarm information that a user cannot determine a processing mode temporarily, and the like.
S450, if the alarm information which does not need the dispatching processing meets the preset condition, the alarm information is isolated, and the alarm information is stored in an isolated alarm area.
Specifically, if the user determines that the alarm information meets the preset condition, the alarm information may have a special condition, and the device corresponding to the alarm information may automatically recover to a normal state, so that the alarm information may be isolated, and after a period of observation, the delay processing may be performed according to the device state. For example, the warning message meeting the preset condition may be an SVG temperature warning message, in which case the warning message may be isolated to see whether the SVG oil temperature can be automatically recovered, or, for example, the warning message meeting the preset condition may also be an inverter fan state abnormality, in which case the warning message may also be isolated to see whether the inverter fan state can be automatically recovered to normal. The alarm information meeting the preset condition can be separately stored in the isolated alarm area so as to separately observe whether the alarm information is automatically recovered.
And S460, continuously monitoring the running state of the photovoltaic power station equipment corresponding to the alarm information in the isolation alarm area within the set time, and determining whether the alarm information can be automatically recovered within the set time.
