The operation error of the electric energy metering device directly affects the accuracy of the electricity trade calculation, so it's very important to ensure the device working accurately. Based on the electric energy meter condition assessment model, considering economic benefits, management benefits and social benefits, we use fuzzy analytic hierarchy process to establish a rotation meter benefit...
The theoretical analysis is discussed for a class of SISO systems based on the characteristic modeling method. The characteristic model is described as a second-order slowly time-varying linear system. With the property of characteristic model, an adaptive controller is proposed in linear form. We prove that the discrete-time closed-loop system of the characteristic model is exponentially stable....
Subsynchronous resonance risk assessment in power system is mainly accomplished by offline simulation analysis, for a practical project, researchers have to consider all kinds of possible typical system operation modes, which might be a huge amount for a large-scale transmission system. This paper comes up with subsynchronous resonance online monitoring, analyzing and early-warning technologies, applies...
Along with the beginning of the big data era, it becomes difficult to capture, store, search, share, transfer, analyze, and visualize bigger data using the traditional data processing applications. Therefore, the problem is very rigid for many larger companies and research institutes that how to correctly and efficiently extract useful information from the massive data. MapReduce is a programming...
The recognition and suppression of small features from solid B-rep models plays an important role in effectively generating the qualified mesh for analysis. This paper presents an automatic algorithm for recognizing small depression features for the purpose of mesh generation. The innovation of the algorithm lies in the recognition capability for filleted or chamfered depression feature. Results of...
