602 results about "Integration testing" patented technology

Integration testing (sometimes called integration and testing, abbreviated I&T) is the phase in software testing in which individual software modules are combined and tested as a group. Integration testing is conducted to evaluate the compliance of a system or component with specified functional requirements. It occurs after unit testing and before validation testing. Integration testing takes as its input modules that have been unit tested, groups them in larger aggregates, applies tests defined in an integration test plan to those aggregates, and delivers as its output the integrated system ready for system testing.

Simulation modeling method for equivalent simulation of doubly-fed wind-power generator set

InactiveCN102592026AImproving the Efficiency of Electromagnetic Transient Simulation StudiesImprove Simulation EfficiencySpecial data processing applicationsInformation technology support systemFrequency changerSimulation
The invention provides a simulation modeling method for equivalent simulation of a doubly-fed wind-power generator set. A frequency converter of the doubly-fed wind-power generator set is simulated by controlled source. The simulation modeling method includes the following steps of (1), building a model of a circuit of the doubly-fed wind-power generator set; (2) building an equivalent model of the doubly-fed wind-power generator set; (3) building a grid-integration testing system of the doubly-fed wind-power generator set; and (4) setting up a testing system for multiple wind-power generator sets, wherein in the step (2), the equivalent model of the doubly-fed wind-power generator set is built on the basis of characteristics of a controlled voltage source of an alternating-current side and a controlled current source of a direct-current side of the frequency converter of the doubly-fed wind-power generator set. By the aid of the simulation modeling method, transient-state characteristics of the doubly-fed wind-power generator set can be simulated accurately, and different characteristics and mutual affection among multiple wind-power generator sets can be computed. High-frequency on and off of fully-controlled devices cannot be taken into consideration, and simulation efficiency is improved greatly. The more the wind-power generator sets are simulated, the more evidently the efficiency is improved, simulation step-length can be increased on the premise of guaranteeing accuracy, and simulation efficiency is improved greatly.
