A simulation model of 230kV substation primary system and TSC+TCR typed dynamic reactive power compensation control system was constituted with RTDS, and the feasibility of control system with a case was validated. The control system was to monitor the variation of power system equivalent susceptance with sampling the power system voltage, established the relationships between power system susceptance and the firing angle of TCR, adjusted TSC switch and TCR firing angle to dynamically compensate the reactive power of power system. The simulation results demonstrate that the control system can guarantee power system voltage stability and real-time adjust power factor.
In order to modify present simulation and test system of DT-100 Short-wave Radio’s Power Amplifier, a kind of automatic test system for short wave radio’s power amplifier is designed here in which virtual instruments and MCU technology are used. Compared with the earlier systems, the new test system avoids many weaknesses, such as complicated simulation test, tedious testing process, and huge manual calculations and has merits of simple operation and accurate assessment all of which provide a better way for existing testing system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
