Besides, the SET sensitivities of two commonly structures are analyzed. To mitigate the SET effects of the LC-VCO, a hardened by design (RHBD) technique was proposed, in which a coupling capacitor is added in parallel with the bias transistor to speed up the discharging of the current pulse deposit. Besides, two ac coupling capacitors are added between the varactors and the LC-tank core to block the voltage distortion at node X and Y caused by SETs. The simulation results indicate that the SET-induced amplitude perturbation and the recovery time of the LC-tank VCO are significantly mitigated.","PeriodicalId":181463,"journal":{"name":"2018 IEEE Canadian Conference on Electrical & Computer Engineering (CCECE)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127620715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, Rossler's system and Chua's system are selected for this study for their practical applications, and the outputs of these two systems are used for the ANN training. The Nonlinear Auto-Regressive(NAR) modelling is used for chaotic time series prediction. The Nonlinear Auto-Regressive with Exogenous Inputs (NARX) modelling is used for generating chaotic time series outputs with varying system parameters as exogenous inputs. The research results show that ANN performs well in modelling chaotic systems. Rossler's attractor is modelled using Radial Basis Function Network(RBFN) and a comparative study between FeedForward Neural Network(FFNN) and RBFN is done. The result shows that RBFN uses more neurons to achieve similar training performance compared to FFNN. The 3-layer ANN architecture with hidden neurons varying from 1 to 16 is designed and trained using MATLAB NN toolbox. In a fixed-point FPGA implementation perspective, a study on the performance of ANN modelling of chaotic systems is very relevant.","PeriodicalId":181463,"journal":{"name":"2018 IEEE Canadian Conference on Electrical & Computer Engineering (CCECE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124190245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Continuity of service of these key assets should be ensured since the defected neutral grounding resistors leave the system unprotected against transient overvoltages and overcurrents and cause false sense of security. An efficient solution is proposed to detect this issue for unit-connected generators that are equipped with the subharmonic injection based generator stator ground protection. The proposed technique demonstrates reliable performance for various conditions of the resistor and power system, observed through comprehensive software analysis. In contrast to existing methods, this technique relies on existing protection and monitoring installations making it an efficient alternative that first, adds more value to existing sub-harmonic injection infrastructures and second, initiates an alarm and prevents ground fault trip in case of failed-short neutral grounding resistor.","PeriodicalId":181463,"journal":{"name":"2018 IEEE Canadian Conference on Electrical & Computer Engineering (CCECE)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121801235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The capacity value estimation methods are discussed briefly, followed by a discussion of the factors that may affect the capacity value of solar resources. The methodology explained here is applicable to any renewable generation. However, the focus of the discussion is on the factors that affect the capacity value of solar resources. Also, the impact of input data on the solar capacity value is included.

A physical channel model in which the angular domain is separated into a finite number of distinct directions is also considered in this paper. Based on the large-scale fading coefficients, a power control method is formulated as an optimization problem in order to maximize the minimum spectral efficiency among the various users under the peak power constraint. This optimization problem is solved by employing a geometric program. The numerical results are conducted by two practical scenarios to evaluate the proposed power control method. In both scenarios, it has been shown that the proposed power control method is superior to other existing schemes in terms of minimum spectral efficiency.","PeriodicalId":181463,"journal":{"name":"2018 IEEE Canadian Conference on Electrical & Computer Engineering (CCECE)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129499517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mis-synchronization can damage equipment (e.g., generators, transformers and breakers). This article describes a centralized synchronization control based on synchrophasors. This control automatically determines running and incoming voltage sources for each breaker using a topological method whose inputs are the states of the breakers and disconnecting switches. A synchronism check (25) is performed on each breaker. In addition, an automatic synchronization (25A) may be performed according to the breaker selected by the operator. Dynamic compensation of the variable delays due to the use of synchrophasors allows the required level of accuracy to be achieved. The control has been implemented on an IEC 61131 platform and tested on a modified IEEE 3-machine 9-bus system simulated in real-time using Hypersim. The overall architecture is fully redundant and it is 61850 compliant.","PeriodicalId":181463,"journal":{"name":"2018 IEEE Canadian Conference on Electrical & Computer Engineering (CCECE)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129778541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both models are developed in PSCAD/EMTDC and their dynamic behavior and computational time are compared against each other. The comparison is conducted for two different dynamic scenarios, fast transients in an event of a fault and slow wind speed variations. It is shown that the simulation results obtained from the average model are comparable to those of the detailed model in terms of accuracy while the simulation time is approximately 15 times faster. The sub-synchronous impedances of both models are calculated via simulation, and it is shown that impedance of the average model resembles the detailed one.
