Abstract

The combined solar and diesel installations are applied in the self-contained systems of power supply. The necessary aspect in such systems’ projecting and scheduling is the assessment of their reliability. However, a number of problems with a stochastic character of natural recourses appears during the reliability analysis of electric installations with renewable energy sources. The photovoltaic solar panels functioning in self-contained systems depend on solar radiation. A theoretical frequency multimatrix method is presented in this article allowing to consider the changes of solar radiation and modes of operations with system element failures. The topological research of the solar-diesel power installation allows one to create a matrix of logical relations between failures, operations and accidents, fixing what kind of failures corresponds to each mode of operation for each condition of solar radiation. The calculation of reliability of the self-contained solar and diesel power station is made by means of the offered theoretical frequency multimatrix method in a distant settlement of the Altai Republic.

光伏太阳能发电系统可靠性理论频率评估

自备供电系统采用太阳能和柴油联合装置。在系统规划和调度中，可靠性评估是必不可少的环节。然而，在对可再生能源电力装置进行可靠性分析时，出现了一些具有自然资源随机性的问题。在独立系统中运行的光伏太阳能电池板依赖于太阳辐射。本文提出了一种考虑系统元件失效时太阳辐射和运行方式变化的理论频率多矩阵方法。太阳能-柴油发电装置的拓扑研究允许人们创建故障、运行和事故之间的逻辑关系矩阵，确定哪种故障对应于每种太阳辐射条件下的每种运行模式。采用提出的理论频率多矩阵法，对阿尔泰共和国某偏远居民点的独立太阳能和柴油电站进行了可靠性计算。
