Abstract

The invention discloses a bridge arm adapter plate for semi-physical testing of a new energy power station and a data processing method. The bridge arm adapter plate comprises a substrate, an FPGA chip is carried on the substrate and is provided with multiple pairs of high-speed optical fiber interfaces, the FPGA chip is used for receiving power module voltage ui sent by RTLAB, and three-phase modulation waves mA, mB and mC sent by a valve base controller, power module synchronizing signals pi and the three-phase SVG current sampling values iA, iB and iC, a valve control instruction for controlling each power module is calculated according to the received data, and the valve control instruction is sent back to the RTLAB. The data interaction and processing functions of the existing SVG controller and RTLAB can be realized by only using one bridge arm adapter plate and two pairs of optical fibers, a special optical fiber plate, a photoelectric conversion module and a communication adapter plate are not needed, the design complexity of the controller is simplified, and the bridge arm adapter plate has the advantages of low development cost and high expandability.

Description

technical field [0001] The invention belongs to the technical field of power station testing, and in particular relates to a software implementation strategy of an SVG valve-base controller used for semi-physical testing of new energy power stations. Background technique [0002] With the rapid development of modern power grids, the massive access of new energy sources, the grid-connected operation of AC and DC power grids, and the wide application of nonlinear loads and impact loads such as high-voltage and large-capacity power electronic equipment, power quality problems in power grids have become increasingly prominent. Static var generator (SVG for short) has been used more and more because of its fast dynamic response and strong ability to suppress voltage mutations. The network source coordination experiment connects the power grid and SVG based on the RTLAB platform through the semi-physical method, changes the relevant parameters of the semi-physical model, and manuf...
