Abstract

The invention provides a voltage regulator simulator, belongs to the field of electrical measurements, and particularly relates to a voltage regulator simulating testing device used in the direct current control and protection system simulation study of direct current high-voltage transmission equipment. Direct current voltage signals are connected to a second arithmetic operation element through a first arithmetic operation element and an absolute value arithmetic device, the second arithmetic operation element is connected to a first mode selective switch and a first proportional component through an inertia element, the first mode selective switch is connected to an integrator and is connected to a first speed limiting device through a second proportional component, an output end of a bound regulation module is connected to a bound regulation input end of the integrator, an output end of the first speed limiting device and an output end of the integrator are connected to a second speed limiting device through a third arithmetic operation element, and a voltage regulation signal output end is formed. By means of the voltage regulator simulator, the operating state of a direct current control and protection device can be simulated and reflected truly, and corresponding simulation results are supplied to the study or design of the direct current control and protection device.

Description

technical field [0001] The invention belongs to the field of electrical measurement, and in particular relates to a voltage regulator simulation test device used for simulation research of a DC control and protection system of high-voltage direct current transmission equipment. Background technique [0002] The ever-increasing demand for electricity has led to the development of power transmission systems in the direction of long distance, large capacity and high stability. As the construction projects of UHV AC transmission projects and HVDC transmission projects in various power grid regions continue to increase, the power grids in areas where power consumption is concentrated show obvious characteristics of UHV AC-DC hybrid receiving-end power grids with multi-DC feeds. The power grid structure is tight, and the electrical distance between multiple AC and DC lines is closer. After the UHV and EHV AC systems fail, it is easy to cause multiple DCs including high-voltage DCs...
