The Time-domain Modeling and Simulation of The Submerged Arc Furnace and Its Power Regulation Characteristics
摘要
Abstract
The load of a submerged arc furnace has many advantages,such as large single-unit regulation capacity,good communication conditions,easy control,and low economic retrofitting,making it an important flexible regulation resource for the power grid.However,there is currently a lack of effective digital simulation methods for modeling submerged arc furnace systems and their regulation characteristics.A time-domain digital simulation model for the power supply system of an industrial submerged arc furnace was established,which included an electric furnace transformer,short network,furnace body,and reactive power compensation,based on the actual electrical operating conditions of the submerged arc furnace.The power regulation characteristics of the submerged arc furnace were determined by representing the electrode regulation link with the time-varying arc length calculated through the Newton downhill method.The equivalent time-varying resistance was obtained by solving the arc differential equation using the Runge-Kutta method,enabling simulation of the power regulation process of the submerged arc furnace.This was achieved by encapsulating it with a custom module and integrating it with the system model to realize time-domain digital simulation.It is applicable to both AC submerged arc furnace and various electrode control strategies,and can be widely used for simulating the load characteristics of submerged arc furnace,flexibility resource assessment,and as a simulation platform for participating in grid interaction research.关键词
