An Analytical Research Technique for Secondary Power Source Statistical Dynamics

The statistical dynamics of secondary power sources (SPSs) is considered using the mathematical apparatus of automatic control theory. The required assumptions for the calculations are set. The possibility of a random value of the SPS output voltage distributed according to the normal law is established. Changes in the load and voltage fluctuations of the exterior network are taken as disturbing factors affecting an SPS. Possible combinations of such factors are considered. A mathematical expectation and variance are used to estimate the output coordinate. As an example, analytical dependences are obtained for calculating the output coordinate parameters for two simplest power sources.
