Schedule of the Total Sum of Loads from Electrical Brooders with the Two-Position Temperature Regulators

Abstract

The time heating constants for various means of heating (such as infrared lamps, ordinary umbrella brooders, electrically heated concrete floors, etc.) are very different from each other. Due to the different inertia of the electrical schedules, the heaters of the two types are completely different. Despite the significant discrepancy between the work schedules of the heaters of various types, the total schedule of their work can be described in general form, if we operate not with the actual heater on and off times, but with their relative values and take the pulse duty cycle from 0 to 1.The expected value, variance, and standard deviation are expressing the nature of the total load at a given time. In order to correctly predict the graph over time, in addition to the specified parameters, it is also necessary to know the speed (pace) of the change in the implementation of the graph. For this, the load graph is usually examined from the standpoint of the theory of random functions, according to which the load graph is considered as a random function.The results of the calculations coincide fairly accurately with the data obtained from the register of brooders.The considered calculation example shows the possibility of determining the average temporal characteristics of the total electrical load curve from a group of electric heaters with two-position temperature regulators operating independently of each other, from the dynamics of temperature control even in the absence of an experimental load curve from one brooder.
