Embodiment Construction

[0018] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0019] Such as figure 1 Shown, a kind of solar array management method comprises the steps:

[0020] Step 1: Check the open circuit voltage, operating voltage, open circuit current, operating current and total operating current of each solar array one by one after every self-inspection cycle.

[0021] We use the solar array to perform regular self-inspection, and the self-inspection cycle can be automatically adjusted according to the sunshine state, day and night. During the day, the self-inspection takes about 10 minutes, and at night or when the sun is weak, it takes half an hour to an hour. Self-inspection once, so that the failure can be detected in time, and the loss of solar energy utilization rate caused by self-inspection can be minimized.

[0022] During self-inspection, each square array has a state of being on an...

Abstract

The invention discloses a solar array management method, which comprises the following steps: detecting the open circuit voltage, the working voltage, the open circuit current, the working current and the total working current of each solar array one by one every two self-inspection periods; determining whether a fault occurs in the solar array according to the open circuit voltage, the working current, the open circuit current and the working circuit and, if so, adding one to a counter; and determining whether the number of the counter is equal to a preset value and, if so, sending alarm. The fault can be determined according to the fact that the number of the counter is equal to the preset value other than according to one result, thereby maximally reducing error determination, obviating false alarm and improving alarm accuracy.

Description

technical field [0001] The invention relates to a solar array management method. Background technique [0002] At present, solar array management schemes are different for different manufacturers, but they all have different shortcomings. For example, the solar array management only judges the overvoltage and overcurrent of the solar array and the loss of the array. Failure to identify and handle other fault states may easily lead to confusion and inefficiency in battery management. Moreover, the existing solar array management scheme is prone to misjudgment, but cannot detect real faults. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above deficiencies, and propose a solar array management method to reduce misjudgment. [0004] Technical problem of the present invention is solved by following technical scheme: [0005] A method for managing a solar array, comprising the following steps: Step 1: detecti...
