These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0047] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0048] First, the terms involved in this application are explained:

[0049] Five remotes: It is the abbreviation of dispatching automation telemetering, telesignaling, remote control, remote adjustment and remote viewing in the power system; among them, telesignaling (TS) refers to the remote status signal, usually written as YX; it refers to the remote transmission of the status signals of electrical equipment in power plants and substations within the power dispatching range to the dispatching center, and telemetering is the connection of equipment so that various signals of the equipment can be transmitted to the telecontrol screen of the transmitting terminal of the power station through telesignaling, and the telecontrol screen will then transmit them back to the dispatching through various signals.

[0050] AGC refers to: Automatic Generation Control (AGC), which is one of the paid auxiliary services provided by grid-connected power plants. Generators follow the instructions issued by the power dispatching and trading agency within the specified output adjustment range, and adjust the power output in real time according to a certain adjustment rate to meet the power system frequency and tie line power control requirements. In other words, automatic generation control (AGC) makes secondary adjustments to the output of some units in the power grid to meet the control target requirements; its basic functions are: load frequency control (LFC), economic dispatch control (EDC), reserve capacity monitoring (RM), AGC performance monitoring (AGC PM), tie line deviation control (TBC), etc.

[0051] The specific application scenarios of this application are as follows Figure 1As shown, there are multiple power stations in the area, including power station 101, power station 102, power station 103, power station 104..., and multiple power stations generate electricity through different power generation types such as photovoltaic power generation, wind power generation or new power generation such as nuclear energy. For example, power station 101 adopts photovoltaic power generation, power station 102 adopts wind power generation, and power station 103 adopts new power generation.

[0052] Usually, when monitoring the power data of multiple power stations in a region, a single power station method is used to check the corresponding power data, etc. However, when the number of power stations connected to the regional power system is large and the voltage equipment is large, the power data of each power station is inspected and checked through the existing monitoring method, resulting in a long inspection cycle and frequent switching of the monitoring screen, causing the system to need to process a large amount of data, increasing the system burden, and at the same time, it is impossible to conduct overall and comprehensive monitoring, and it is impossible to detect power failures and abnormalities in time.

[0053] The present application provides a centralized monitoring method for power stations based on an electric power system, aiming to solve the technical problem in the prior art that the power data of multiple power stations cannot be checked comprehensively and holistically at the same time. The present application divides the power station layer, the middle layer and the regional layer. The substation layer displays the power data of multiple power stations, the middle layer displays the power data of power stations of the same power generation type, and the regional layer displays the power data of all power stations in the region. The power data between the three layers are linked through the relationship of OR gate and accumulation, and displayed in the same monitoring screen. There is no need to frequently monitor the household screen, and the power stations in the entire area can be monitored simultaneously from the overall comprehensiveness, reducing the amount of data processed by the system.

[0054] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0055] Figure 2 The process of the centralized monitoring method of a power station based on the power system provided in the embodiment of the present application is as follows: Figure 1 ,like Figure 2 As shown, the method includes:

[0056] S201. Obtain a power monitoring request, where the power monitoring request carries an area identifier of an area to be monitored.

[0057] In order to effectively monitor the power data of power plants such as daily power generation, power generation, etc., as well as power faults such as fire signals and fault information, and to facilitate the adjustment and control of the power output and power supply of each power plant, multiple power plants can be divided into multiple areas according to factors such as geographical location, and each area can be marked, so that in the power monitoring process, the power plants can be monitored more accurately and the power data can be better consulted and analyzed.

[0058] At the same time, in order to enable the power monitoring system to access the power data of each power station more quickly and conveniently, and to comprehensively monitor each power station, and to avoid problems such as excessive system burden and slow response speed caused by excessive data processing, multiple power stations can be divided and marked. This can not only reduce the data processing burden of the monitoring system to a certain extent, but also comprehensively and accurately monitor the power data and power failures of each power station.

[0059] Based on the obtained power monitoring request and the area identifier carried in the power monitoring request, it is known which monitoring area in the entire power system needs to monitor multiple power plants, and the power data, power faults, etc. of all power plants in the area can be obtained.

[0060] S202. According to the regional identifier, obtain a knowledge graph corresponding to the pre-stored regional identifier, the knowledge graph includes a monitoring area layer corresponding to the regional identifier, a monitoring middle layer divided based on the power station type under the monitoring area layer, and a substation layer corresponding to each power station type, each substation layer includes a power plant of the corresponding power station type.

[0061] The knowledge graph is designed to enable monitoring personnel to obtain information such as power data, power failures, and power station types of each power station through the monitoring interface. It can describe each type of power data, such as daily power generation, power generation, and the power station type of each power station. For example, by obtaining the daily power generation of power station A, the knowledge graph can be displayed in the form of a bar chart, pie chart, etc., and the graph can be updated synchronously according to the changes in the daily power generation of power station A, thereby realizing accurate monitoring of the daily power generation data of power station A. In addition, the power station type of power station A can also be obtained and described through the knowledge graph.

[0062] The knowledge graph not only includes the regional monitoring layer corresponding to the regional identification, but also includes the monitoring intermediate layer based on the power station type under the monitoring regional layer and the substation layer corresponding to each power station type. Each substation layer includes the power station of the corresponding power station type. The knowledge graph of the regional layer can be the same or different from the knowledge graphs of the intermediate layer and the substation layer. Accordingly, the knowledge graphs of various power data and power faults of the substation layer, intermediate layer or regional layer can be the same or different.

[0063] The knowledge graph of each type of power data at the substation layer reflects the power data information of any power plant and the type of power plant; the knowledge graph of each type of power data at the middle layer reflects the total power data information of power plants of the same power plant type; the knowledge graph of each type of power data at the regional layer reflects the power data information of the power plants in the region.

[0064] The power station type includes the form in which each power station generates electricity, for example, the first power station generates electricity through photovoltaic power, the second power station generates electricity through wind power, and the third power station generates electricity through new forms such as thermal power generation and nuclear power generation; multiple power stations in each monitoring area can generate electricity through one or more power generation forms.

[0065] S203. Obtain monitoring data of each power plant according to the knowledge graph, and display the power system monitoring data on the display interface based on the knowledge graph. The power system monitoring data includes monitoring data corresponding to the monitoring area layer, the monitoring middle layer and the substation layer.

[0066] The monitoring data includes power data such as AGC sent value, actual power and daily power generation, as well as power faults such as fire signal, power limit signal and fault signal.

[0067] The monitoring data of each power plant is obtained through the knowledge graph, and the various power data of the power system are displayed on the display interface. On the same display interface, the corresponding monitoring data of the monitoring area layer, the monitoring middle layer and the substation layer are displayed respectively, which is convenient for monitoring personnel to obtain various monitoring data of each power plant from the same interface. At the same time, the total monitoring data of each power generation type in the area and the total monitoring data of all power plants in the area can also be obtained.

[0068] The embodiment of the present application provides a centralized monitoring method for power stations based on an electric power system, which obtains an electric power monitoring request, which carries an area identifier of an area to be monitored; according to the area identifier, obtains a knowledge graph corresponding to a pre-stored area identifier, the knowledge graph includes a monitoring area layer corresponding to the area identifier, a monitoring middle layer divided based on the power station type under the monitoring area layer, and a substation layer corresponding to each power station type, each substation layer includes a power station of the corresponding power station type; obtains monitoring data of each power station according to the knowledge graph, and displays the electric power system monitoring data on a display interface based on the knowledge graph, the electric power system monitoring data includes monitoring data corresponding to the monitoring area layer, the monitoring middle layer, and the substation layer; the monitoring method provided by the embodiment of the present application realizes effective monitoring of multiple power stations in the area, and through the establishment of a knowledge graph, enables personnel to easily obtain various monitoring data of each power station, power stations of each power generation type, and power stations in the entire area, reduces the switching of monitoring interfaces, reduces the amount of data processing in the electric power system, facilitates access and inspection, and has a short inspection cycle.

[0069] Figure 3 The process of the centralized monitoring method of a power station based on the power system provided in the embodiment of the present application is as follows: Figure 2 ,like Figure 3 As shown,

[0070] S301. According to the location information of the area to be monitored and each power station, the power stations covered by the area to be monitored are obtained, and an area identifier and a monitoring area layer corresponding to the area to be monitored are generated.

[0071] The location information may be the geographical coordinates, address information or administrative area of ​​each power plant; by acquiring the power plants covered in the area to be monitored, the area identification corresponding to the area to be monitored and the monitoring area layer are generated according to the location information of the power plants and the area to be monitored.

[0072] S302: Classify power plants of the same type according to their power plant types to obtain a monitoring middle layer and a substation layer corresponding to each power plant type.

[0073] Power stations of the same type are classified according to their power station types. For example, if the power station type of power station A1 is wind power generation, the power station type of power station A2 is photovoltaic power generation, and the power station type of power station A3 is wind power generation, then power stations A1 and A3 are of the same type. Those skilled in the art will appreciate that power stations A1, A2, and A3 are described only for the purpose of distinction and clarity without any other special instructions or limitations.

[0074] After classification, a monitoring middle layer is obtained, including power plants classified into different power plant types, and a substation layer is obtained, including each power plant corresponding to each power plant type.

[0075] Furthermore, after completing the above steps, a knowledge graph is constructed based on the monitoring area layer, the monitoring middle layer and the substation layer, and associated storage is performed based on the area identifier and the knowledge graph; the following is a detailed description of how to construct a knowledge graph and associate storage based on the area identifier and the knowledge graph.

[0076] The knowledge graph also includes the attributes of the data items in each layer of data; wherein, the attributes of the data items in each layer of data include signal attributes and data attributes; the data value of the upper layer data is obtained by summing up the data values ​​of the associated lower layer data; correspondingly, the power system monitoring data displayed on the display interface includes: signal display based on signal attributes at each layer and data value display based on data attributes at each layer.

[0077] The knowledge graph includes the monitoring area layer, the monitoring middle layer and the monitoring substation layer, each data attribute in each monitoring layer, such as AGC sent value, daily power generation, etc.; each signal attribute such as fire signal, fault information, etc., and also includes the power station type of each power station.

[0078] S303, display the monitoring area layer, the monitoring middle layer and the substation layer as well as the data items and data logic relationships of each layer, wherein the data logic relationships include accumulation attributes and OR gate attributes.

[0079] S304 , drawing a virtual connection between the signal attribute and the OR gate attribute, and a virtual connection between the data attribute and the accumulation attribute.

[0080] Signal attributes include: one or more of fire signal, power limit signal or fault signal; data attributes include: one or more of AGC sent value, actual power or daily power generation; the data value of the substation layer is the data value corresponding to the data attribute of each substation, the data value of the monitoring middle layer is the cumulative value of the data value of the same data attribute of the same type of power plant, and the data value of the monitoring area layer is the cumulative value of the data value of the same data attribute of different types of power plants in the monitoring middle layer.

[0081] The data value of each data attribute in the monitoring area layer is obtained by accumulating the data value of the same data attribute corresponding to it in the monitoring middle layer, and the data value of each data attribute in the monitoring middle layer is obtained by accumulating the data value of the corresponding data attribute in the monitoring substation layer; for example: the daily power generation of power station A1 is x, the AGC value sent by power station A2 is z, and the daily power generation of power station A3 is y. Since power stations A1 and A3 are of the same power station type, the daily power generation of the power station of wind power generation type in the monitoring middle layer is x+y.

[0082] The signal display of each signal attribute includes a signal category and an event occurrence flag, and the event occurrence flag is used to indicate whether the event corresponding to each signal occurs.

[0083] For the signal display of signal attributes, the signal display of the monitoring area layer is based on the corresponding signal display of the monitoring middle layer, and the signal display of the monitoring middle layer is based on the corresponding signal display of the substation layer; for example, if a fire signal is displayed in the signal attribute of power plant A1, then in the monitoring middle layer, a fire signal is also displayed in the power station type of wind power generation, while other power station types in the monitoring middle layer do not display fire signals. In the monitoring area layer, a fire signal is also displayed based on the signal attributes of the monitoring middle layer.

[0084] S305. Build a knowledge graph based on the monitoring area layer, the monitoring middle layer, the substation layer structure and the virtual connection.

[0085] By virtually connecting the monitoring area layer, the monitoring middle layer and the substation layer, a knowledge graph is created. Through the knowledge graph, monitoring personnel can obtain the data and signal information of each power station in the monitoring area at the first time.

[0086] For example, Figure 4 As shown, the display interface displays the monitoring data corresponding to the monitoring area layer, the monitoring middle layer and the substation layer in hierarchical order; the monitoring middle layer also displays a progress icon, which is used to dynamically display the power generation load; each monitoring middle layer and substation layer also displays a power station type icon, wherein different power station types have corresponding power station type icons of different colors and shapes.

[0087] The substation layer displays the AGC sent value, actual power, daily power generation, power limit signal, fault signal and fire signal of each power station, and also displays whether the power station type of each power station is photovoltaic power generation, wind power generation, or new power generation types such as nuclear power generation, hydropower generation, etc. The monitoring middle layer is classified according to the power station type, and the regional layer displays various data values ​​and signals of the power stations in the monitoring area. By constructing a knowledge graph, the monitoring personnel can quickly and accurately obtain the monitoring information of each power station through the knowledge graph. They can obtain the distribution of each power station type and the monitoring information of each power station type in the area, and then they can make adjustments and respond to various faults in time. While solving the faults, they can make adjustments to ensure the output and supply of electricity, so that the normal power supply to the area will not be impossible due to the failure of a power station to generate electricity. There is no need to frequently switch the monitoring screen, which will cause the data processing burden of the monitoring system, and comprehensive and accurate centralized monitoring can be carried out.

The power system monitoring data includes the monitoring data corresponding to the monitoring area layer, the monitoring middle layer and the substation layer.

[0092] The processing module 502 is further used to obtain the power generation stations covered by the area to be monitored according to the location information of the area to be monitored and each power generation station, and generate an area identification and a monitoring area layer corresponding to the area to be monitored.

[0093] The processing module 502 is also used to classify power plants of the same type according to the power plant type of the power plant, and obtain a monitoring middle layer and a substation layer corresponding to each power plant type.

[0094] The processing module 502 is also used to construct the knowledge graph according to the monitoring area layer, the monitoring middle layer and the substation layer, and to perform associated storage based on the area identifier and the knowledge graph.

[0095] The processing module 502 is also used to display the monitoring area layer, the monitoring middle layer and the substation layer as well as the data items and data logic relationships of each layer. The data logic relationships include accumulation attributes and OR gate attributes.

[0096] The processing module 502 is further used to draw a virtual connection between the signal attribute and the OR gate attribute, and a virtual connection between the data attribute and the accumulation attribute.

[0097] The processing module 502 is also used to build a knowledge graph based on the monitoring area layer, the monitoring middle layer and the substation layer structure and virtual connections.
