That is, n types of power station apparatuses are all corresponding to respective weight values, and in the embodiment of the present application, the correspondence between the n types of power station apparatuses and the first weight value is pre-stored in a terminal or a server, and may be stored in a table form, and the correspondence between the n types of power station apparatuses and the first weight value is shown in the following table 1.

Table 1: n-class power station equipment-first weight value corresponding relation table

Power station equipment serial number	Type of plant equipment	First weight value
			D ₁	Box transformer	10
D ₂	Centralized inverter	8
			D ₃	String inverter	4
D ₄	Direct current collection flow box	3
			D ₅	AC collecting box	5
D ₆	Ammeter	1
			D ₇	Meteorological station	1

When the fault equipment in the photovoltaic power station is maintained, the importance degree of the fault can be estimated according to the prompt information displayed in the terminal, if the fault equipment exists in the box-type transformer equipment, operation and maintenance personnel need to immediately maintain the fault box-type transformer equipment, if the electricity meter exists in the fault equipment, the fault electricity meter equipment can be selectively maintained.

The corresponding relation between the running state data and the running health condition of the box transformer equipment is as follows: shutdown-unhealthy status, night status-healthy status, normal operation-healthy status.

And when the running state data sent by the box-type substation equipment in the photovoltaic power station to the server indicate that the box-type substation equipment is in the off-line state, the server determines that the running health condition of the box-type substation equipment is unhealthy according to the off-line state.

The running health condition comprises any one of a health state, a sub-health state and an unhealthy state, wherein the health state corresponds to the first sub-weight, the sub-health state corresponds to the second sub-weight, and the unhealthy state corresponds to the third sub-weight.

Fig. 6 is a flowchart of a method for determining a state of a photovoltaic power plant according to an exemplary embodiment of the present application, and the method is applied to a server, for example, as shown in fig. 6, and includes:

in step 601, the device runs data acquisition.

In the embodiment of the application, the operation state data of all power station equipment in each photovoltaic power station are collected, wherein the power station equipment comprises at least one of a box transformer, a centralized inverter, a string inverter, a direct current combiner box, an alternating current combiner box, an ammeter and a weather station, and the centralized inverter and the string inverter are displayed according to the inverters when displayed on a terminal interface.

In some embodiments, the server collects operational data corresponding to power plant equipment in all photovoltaic power plants in the area to which the server belongs, the operational data including at least one of power generation, weather, and cumulative radiation.

Alternatively, the importance of the various power plant devices in different photovoltaic power plants is different, for example, the importance of the box-section devices in the photovoltaic power plant a is greater than that of the inverter devices. Illustratively, n types of power station equipment in the photovoltaic power station correspond to n first weight values, wherein the ith first weight value corresponds to the ith equipment type, and n is an integer greater than 1. Optionally, an operation and maintenance person can automatically adjust first weight values corresponding to n types of power station equipment in a terminal display interface, and illustratively, the first weight value corresponding to box-type substation equipment in the photovoltaic power station a is 10, and when the operation and maintenance person debugs the importance degree of the box-type substation equipment, the first weight value 10 corresponding to the box-type substation equipment is changed to 5.

Step 602, device status determination.

In some embodiments, the server determines an operating state of n types of power station equipment in the photovoltaic power station according to the obtained operating data. Illustratively, the operation states corresponding to the box-type substation equipment comprise any one of shutdown, night state and normal operation. The corresponding relation exists between the running state and the running health condition of the power station equipment, and optionally, the corresponding relation can be pre-stored in a server or self-defined by operation and maintenance personnel; for example, the off-stream state corresponds to an unhealthy state and the night state corresponds to a healthy state.

Optionally, in the terminal display interface, specific conditions of the power station equipment in each photovoltaic power station are displayed in the form of cards, where the specific conditions include at least one of healthy operation conditions of the power station, operation data of the power station, problematic equipment types, and total number corresponding to the problematic equipment types. And operation and maintenance personnel can visually check the health condition corresponding to each photovoltaic power station through the terminal display interface, and if the detailed information of one photovoltaic power station is required to be checked further, the detailed checking of the equipment information with problems can be performed by triggering a control preset in the card.

In some embodiments, the server determines an operation state corresponding to each device according to the operation data sent by each device in each type of n types of power station devices, counts the number of power station devices in each type of power station device under each operation state data, and determines an operation health condition corresponding to each device. In some embodiments, the health type in the running health condition also corresponds to a second weight value. The running health condition comprises any one of a health state, a sub-health state and an unhealthy state, wherein the health state corresponds to the first sub-weight, the sub-health state corresponds to the second sub-weight, and the unhealthy state corresponds to the third sub-weight.

And step 603, calculating the health degree score of the power station.

In some embodiments, the server obtains a first weight value and a second weight value corresponding to the power station equipment according to table 1 and table 2, wherein the first weight value is used for indicating the importance degree of the power station equipment in the photovoltaic power station, and the second weight value is used for indicating the importance degree of the operation health degree corresponding to the power station equipment.

Based on the first weight value and the second weight value, the server acquires the power station health degree corresponding to the photovoltaic power station by using formulas 1 to 3, and feeds the power station health degree back to a preset position of the terminal for display.

Step 604, whether a status health grouping needs to be adjusted.

After checking the health degree score of a certain photovoltaic power station, operation and maintenance personnel perform self-defined setting on a second weight value corresponding to the operation health condition corresponding to the power station equipment. For example, the terminal responds to operation and maintenance personnel triggering operation for checking the power station health degree score, the health degree of the photovoltaic power station is calculated by utilizing a pre-stored weight value (comprising a first weight value and a second weight value), and a calculation result is obtained and then fed back to the terminal; the operation and maintenance personnel adjust the second weight value corresponding to the power station equipment and the importance degree duty ratio of the first weight value through triggering the control button set by the index, and before adjustment, the first weight value corresponding to the box transformer equipment is schematically 9, the first sub-weight (representing the importance degree occupied by the running health condition of the box transformer equipment as the health state) in the second weight value is 5, the operation and maintenance personnel adjust the first weight value and the first sub-weight, and the adjusted first weight value is 4, and the first sub-weight is 2.

When the operation and maintenance personnel decides that the state health degree group needs to be adjusted, step 605 is executed, and if the state health degree group does not need to be adjusted, step 606 is executed.

Step 605 alters the device state health groupings.

The first and second weight values of the plant are adjusted in response via step 604, and the adjusted first and second weight values are applied to the subsequent plant health calculations in equations 1-3.

Step 606, outputting the power station health.

And the server completes the calculation of the power station health degree of the photovoltaic power station by using formulas 1 to 3 based on the acquired operation data corresponding to the power station equipment, the first weight value and the second weight value.

The server calls a power station health condition matching table (preset power station scoring standard) corresponding to the table 3, and determines a photovoltaic power station with the power station health degree being more than 0.8 and no power station equipment in a state of poor communication as a health state; determining a photovoltaic power station with the power station health degree of more than or equal to 0.6 and less than or equal to 0.8 as a sub-health state; determining a photovoltaic power station with the power station health degree less than 0.6 as an unhealthy state; and determining that the communication is poor in the photovoltaic power station with the power station health degree being more than 0.8 and the power station equipment in the photovoltaic power station in a state of poor communication.

In step 607, whether the plant scoring criteria need to be adjusted.

The server determines the power station health degree of the photovoltaic power station by utilizing a pre-stored power station health condition matching table, and then displays the power station health degree in a terminal interface; the operation and maintenance personnel decide whether to adjust the power station scoring standard of the current photovoltaic power station. If adjustment is required, step 608 is performed; if no adjustment is required, step 609 is performed.

Step 608, altering the power plant health scoring criteria.

The operation and maintenance personnel adjust the preset power station scoring standard and obtain the adjusted power station scoring standard, and optionally, the server receives the adjusted power station scoring standard and replaces the preset power station scoring standard; or the server sets the adjusted power station scoring standard as a first scoring standard, stores the last set power station scoring standard in a list form, outputs the list when the operation and maintenance personnel perform power station health scoring, and calculates the power station health of the photovoltaic power station based on the selection operation of the operation and maintenance personnel by the operation and maintenance personnel.

In step 609, the terminal displays the health condition.

After the server finishes the calculation of the power station health degree of the photovoltaic power stations, the specific conditions of the photovoltaic power stations are fed back to the terminal for display. Referring to fig. 7, an interface diagram showing the healthy operation state of the photovoltaic power station in the terminal is shown in fig. 7.

As shown in fig. 7, all photovoltaic power stations are displayed in a card form in a power station list interface 701, and the quantity information corresponding to each health condition of all the photovoltaic power stations is summarized into a first area 702, wherein the first area 702 displays "all states 4", "unhealthy 0", "sub-healthy 2", "healthy 1" and "poor communication 1", which are used for indicating that the total number of the photovoltaic power stations is 4, the number of the photovoltaic power stations in the unhealthy state is 0, the number of the photovoltaic power stations in the sub-healthy state is 2, the number of the photovoltaic power stations in the healthy state is 1 and the number of the photovoltaic power stations in the poor communication state is 1; optionally, the display priorities of "unhealthy", "sub-healthy", "healthy" and "bad communication" may be preset or may be custom set by an operator, which is not limited in the present application.

The operation condition of each photovoltaic power station is displayed in the power station list interface 701 in the form of a card, wherein the card 703 user indicates the operation condition of 'Hua Ruiguang photovoltaic power station', the card 703 comprises a first warning area 704 and a normal display area 705, the first warning area 704 displays different warning colors or marks according to the health condition of the first sub-card 706, optionally, when the first sub-card 706 displays 'sub-health', the color of the first warning area 704 is set to yellow, when the first sub-card 706 displays 'health', the color of the first warning area 704 is set to green, when the first sub-card 706 displays 'poor communication', the color of the first warning area 704 is set to gray, and when the first sub-card 706 displays 'unhealthy', the color of the first warning area 704 is set to red; the normal display area 705 is used to display the operating data of the photovoltaic power plant. The corresponding health condition of the photovoltaic power plant is displayed in a first sub-card 706, the first sub-card 706 is used for indicating that the health condition of the power plant of the "Hua Ruiguang v power plant" is "sub-health", and the display state of the first warning area 704 is yellow. A problem display area 707 is further included in the normal display area 705, where the problem display area 707 is used to indicate that the type of power station equipment, the corresponding operating state condition, and the corresponding equipment number of the problem exist in the "Hua Ruiguang v power station", and the equipment number of the box-type substation equipment in the off-line state in the "Hua Ruiguang v power station" is schematically 1.
