Traditional off-grid frequencies The frequency conversion AC test power supply mostly adopts the frequency conversion generator set scheme. With the development of power electronic technology, embedded technology and control technology, the The experimental variable frequency power supply (TPS) controlled by advanced digital converter technology has begun to be widely used. This type of power supply has high power quality, It has the characteristics of fast response speed, convenient adjustment, small footprint, simple expansion and upgrade, and has more excellent energy saving effect and operation convenience. Convenient and energy-saving test power supply. The experimental variable frequency power supply (TPS) has been widely used in many industries and fields in my country, for example, as a rotating electrical machine and power transformer. The detection power supply of the wind turbine generator, the power grid simulation power supply of the wind turbine, etc. As the basic inspection and testing in the manufacturing and testing process equipment, and its standards play a very important role. The test variable frequency power supply (TPS) is closely related to the general frequency converter, although the topology and control technology of its main core components It is very similar to the general-purpose inverter as a speed-regulating electrical system, but as a test power supply, there are various Different requirements, and there is a big difference with the general frequency conversion power supply. It can be considered that the speed regulating electric drive system (PDS) and the variable frequency power supply for testing (TPS) are two system branches based on the Basic Transmission Module (BDM). The purpose of this document is to specify the corresponding conditions of use, preferred ratings, technical requirements, test methods, inspection rules and marking, packaging, shipping Transport and storage, etc., promote the improvement of product technology and product quality, thereby leading and promoting the technological progress of the entire industry. General specification for variable frequency power supplies for testing1 ScopeThis document specifies the index, rating, method of determining performance and test requirements, marking, packaging, transportation General technical requirements such as transmission and storage, and specify specific technologies in the testing of rotating electrical machines and power transformers, as well as in power grid simulation application scenarios Require. This document applies to the rated input voltage of AC 35kV and below, the rated input frequency of 50Hz or 60Hz, the output voltage is not large It is a test variable frequency power supply (TPS) with an output frequency of not more than 500Hz and an output rated power of not less than 10kW at 35kV. The frequency conversion power supply (TPS) used for testing in switchgear, inverter and other similar products can refer to this document. Note. See Appendix A and Appendix B for the application examples of the test variable frequency power supply (TPS) in the motor industry and the converter industry test.2 Normative referencesThe contents of the following documents constitute essential provisions of this document through normative references in the text.
