Problems solved by technology
[0003] For the monitoring of inverter power generation, most monitoring systems use a tree structure display to represent the number of inverters under the power station. One inverter corresponds to one or more photovoltaic arrays, but the array It is not intuitive to use a tree structure to display

Embodiment Construction
[0037] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.
[0038] see Figure 2 to Figure 4 As shown, the visualization method for monitoring the operating status of the photovoltaic power station inverter system of the present invention includes the following steps:
[0039] (1) The monitoring system collects the power generation and radiation value of each inverter in different time periods;
[0040] (2) The monitoring system plots the collected power generation and radiation values of all inverters in different time periods on the horizontal axis as time, and the vertical axis is the first chart of the total power generation and radiation value middle;
[0041] (3) The user judges whether the inverter system is operating normally according to the total power generation and total irradiation value in the same time period;
[0042] (4) If the inverter system ...

The invention relates to a photovoltaic power station inverter system operation state monitoring visualization method. The photovoltaic power station inverter system operation state monitoring visualization method is mainly achieved through two charts, namely a first chart and a second chart, wherein the first chart shows a relationship between the power generation total amount and the irradiation total amount in all time periods, a user can examine the power generation conditions, namely the second chart, of inverters in the time period if the relationship between the power generation total amount and the irradiation total amount is abnormal, a positional relation between the inverters in the second chart and a positional relation between site inverter arrays is consistent, colors of the inverter arrays in the second chart are different, the deeper color shows large power generation amount, and a showing array of the faulted inverter is blank. The photovoltaic power station inverter system operation state monitoring visualization method achieves organic unity of a site structure and monitoring show and a user can find out main reasons of the failure of the corresponding inverters according to the monitoring display information.
Description
technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to inverters, and specifically to a visualization method for monitoring the operating status of inverter systems in photovoltaic power plants. Background technique [0002] The basic structure of a photovoltaic power station: meter>inverter>combiner box>string>components, the main function of the inverter is to convert DC into AC, which is the electricity used in our normal life, and the overall power generation of the power station is almost dominated by it , so in the entire photovoltaic structure, the safety monitoring and maintenance of the inverter cannot be ignored. [0003] For the monitoring of inverter power generation, most monitoring systems use a tree structure display to represent the number of inverters under the power station. One inverter corresponds to one or more photovoltaic arrays, but the array It is not intuitive to use a tree structure...
