Abstract

The invention belongs to the field of electrical measurement and particularly relates to an ignition pulse generator simulating device for simulation study of a direct current control system of high-voltage direct-current power transmission equipment. A double-pole unlocking signal end is connected to a first arithmetical operation element and a second arithmetical operation element via a timer, a protective locking signal end is connected to a Schmitt trigger via a phase inverter, the first arithmetical operation element is connected to a first conjunction gate, an output end of the Schmitt trigger is connected to the first conjunction gate, an output end of the first conjunction gate is connected to an unlocking signal end of a first ignition trigger assembly, the second arithmetical operation element is connected to a second conjunction gate, and the output end of the Schmitt trigger is connected to an unlocking signal end of a second ignition trigger assembly via the second conjunction gate. The ignition pulse generator simulating device can truly simulate and reflect running states of a direct current control and protection device, and provides corresponding simulation results to research or design of the direct current control and protection device.

Description

technical field [0001] The invention belongs to the field of electrical measurement, in particular to an ignition pulse generator 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 to ...
