Embodiment Construction

[0018] The technical solution of the invention will be further described in detail below based on the drawings of the specification and specific examples.

[0019] Such as figure 2 Shown is a schematic diagram of the system structure used to implement the judgment method of the present invention. The figure describes the implementation process of the entire method. The monitoring system collects data such as current, voltage and power, and the field operation and maintenance personnel of the energy storage station input the information of the operation site of the energy storage station. For each parameter, the calculation module automatically calculates the result according to the known reliability evaluation index calculation formula, and stores the result in the real-time database. Threads such as graphs, history storage, reports, etc. perform corresponding operations based on the data in the database, and at the same time send the calculation results to the limit alarm modul...

Abstract

The invention relates to a reliability determination method of high-capacity energy storage equipment. An automatic monitoring system of an energy storage station collects voltages, currents, and powers of all battery piles, battery groups, and single batteries; a calculation module completes calculation of a reliability evaluation index of high-capacity energy storage equipment completely; a limit-value warning module compares the evaluation index with a predetermined limit value to determine whether the index is abnormal; and if so, warning prompting is carried out. The calculation result and the evaluation result are stored historically and functions of historical querying, report manufacturing, and warning prompting are provided. With the method, determination of a reliability index of a high-capacity energy storage station is realized and warning is caries out when the index is abnormal. Meanwhile, the workload of hand-operated calculation of the evaluation index of the operator in the prior art is reduced substantially; the work efficiency is improved; an error caused by hand-operated calculation is minimized; and the calculation result accuracy is improved.

Description

Technical field [0001] The invention belongs to the technical field of power system substation automation, and particularly relates to a reliability judgment method for large-capacity energy storage equipment. Background technique [0002] The reliability evaluation of large-capacity battery energy storage equipment is an important part of power reliability management. Statistics, analysis and evaluation of the reliability of large-capacity battery energy storage equipment provide technical support for the operation and management of battery energy storage stations. [0003] Traditional reliability evaluation mainly relies on artificial statistics of various calculation parameters, and manual calculation according to the calculation formula of each index. The statistics and calculation process are very cumbersome. And the energy storage station needs to calculate the evaluation index every once in a while, which increases a lot of workload. Because it is a human operation, the pos...
