Numerical Modeling of Dynamics of Thermal Power Equipment of the Power unit at the Nazarovo Power Station by Volterra Polynomial

The paper focuses on an approach to the identification of Volterra polynomials. The approach is based on the generalization of the product integration method. An algorithm for the numerical identification of a quadratic scalar Volterra polynomial is proposed. The algorithm is based on the application of test signals in the form of a combination of Heaviside functions and deviating argument. The suggested approach was used for modeling the dynamics of pressure in the condenser of generating unit at the Nazarovo power plant. The results of the calculations have shown sufficient accuracy of the models for practical application.
