Embodiment Construction

[0077] The structure of the present invention will be described in detail below through embodiments and in conjunction with the accompanying drawings.

[0078] The invention includes the description of the iron core structure and working principle of the magnetic control shunt reactor and the simulation modeling method.

[0079] 1. Magnetically controlled shunt reactor core structure

[0080] As shown in Figure 1, the magnetically controlled shunt reactor adopts a single-phase split-core structure. Its structure is a single-phase four-column, in which winding 1 and winding 2 are the primary windings of the controllable reactor, and their terminals with the same name are connected in parallel to the power grid; winding 3 and winding 4 are the secondary windings of the controllable reactor, that is, the excitation winding Or called the control winding; the excitation winding is placed on the inside, and the primary winding is placed on the outside. Under the action of AC volta...

The invention relates to a magnetic control shunt reactor digital simulation modeling method, which is characterized in that the method comprises a decomposition method of an equivalent magnetic circuit, and according to magnetic circuit laws and circuits laws, the magnetic control shunt reactor module can be equivalent to a plurality of saturated transformers and reactor modules; the invention uses saturated transformers and saturated reactors in prior simulation software and forms a magnetic control shunt reactor simulation module, which has clear principles, easy process and realization, has reliable and accurate module, and can be integrated in to prior simulation software to expand prior simulation functions; the digital simulation modeling method of the invention provides effective means for a steady control method and a transient control method of an inspection system.

Description

technical field [0001] The invention relates to a digital simulation modeling method, in particular to a digital simulation modeling method for a magnetically controlled shunt reactor. Background technique [0002] Controllable shunt reactor technology is a technology that coordinates the contradiction between reactive power regulation and overvoltage suppression in ultra-long-distance EHV lines and UHV lines. It is one of the key technologies necessary for the construction of UHV AC power grids, so it has broad applications prospect. The controllable shunt reactor has the advantages of high reliability, low cost, small footprint, and simple operation and maintenance. Its application can not only simplify reactive power voltage control measures, but also improve line transmission power, improve system stability, and limit power frequency It is of great significance and role for the development and construction of ultra-high voltage and ultra-high voltage power grids.
