“…The modal steady-state L i st , transition L , modal effective mass L and free-free L participation fractions are compute using equations (15), (17), (24) and (29), respectively, and the results are shown in figure 3. This figure gives an idea of the difference in magnitude obtained with each method, however the results should be interpreted independently.…”

“…However, the results obtained using equation (32) are in disagreement with those of the modal strain energy, which indicates that the internal load is dominated by the first elastic mode. Using the steady and the transient modal response participation factors, the peak in plane shear force was recovered using equation (19) with (15) and (17), respectively. Table I shows a comparison and percentage error between the recovered load and the actual peak load computed using MSC NASTRAN [53].…”

“…A simple search of the words "modal participation factor" in the open literature quickly reveals that several variants of this concept exist. For instance, in electrical engineering [15][16][17][18] the term MPF refers to the product between the left and the right eigenvectors; other researchers [19][20][21][22] used simple definitions for MPF such as the same term to refer to the components of the eigenvector matrix. On the other hand, [23][24][25][26][27][28] defined different convenient mathematical forms as modal participation factor suitable to their specific applications.…”

In this paper we review different definitions of Modal Participation Factor (MPF) available in the literature and propose a simple classification and unified concept for their application with particular focus in aerospace engineering. A case study is presented to aid the reader understand under what conditions each definition of MPF applies, its physical interpretation and which definitions have the potential to act as response tracking mechanisms during design optimization.

“…Dalam sistem tenaga listrik skala besar, menjaga kontinuitas dan ketersediaan pasokan listrik untuk para konsumen menjadi tujuan utama pada sistem interkoneksi agar tidak menyebabkan melemahnya stabilitas performa sistem. Referensi [3][4][5] telah mengidentifikasi stabilitas sistem tenaga sebagai bagian prasyarat terpenting dan terpercaya selama kurang lebih dari 80 tahun terakhir untuk mendapatkan operasi sistem listrik yang aman. Operasi suatu sistem tenaga listrik diharapkan dapat mempertahankan stabilitas tegangan yang telah menjadi masalah utama dalam perencanaan dan pengoperasian sistem tenaga [6] dan merupakan bagian penting dalam menjaga ketersediaan suplai listrik secara kontinyu dengan kualitas daya yang baik dengan meminimalisasi terjadinya pemadaman listrik (black out) total atau sebagian.…”

Simulasi Under Voltage Load Shedding (UVLS) dengan mempertimbangkan integrasi pembangkit listrik tenaga bayu (PLTB). PLTB yang akan diintegrasikan ke dalam sistem interkoneksi Sulawesi Selatan milik PT. PLN (Persero) berada di daerah Sidrap sekitar 70 MW dengan menggunakan 30 turbin angin, menghasilkan 2,5 MW per turbin dan di daerah Jeneponto sekitar 62,5 MW dengan jumlah turbin angin yang sama. Kondisi angin yang berbeda dapat mempengaruhi sistem tenaga yang menyebabkan gangguan besar atau kecil, baik dalam pelepasan generator atau jalur transmisi. Berdasarkan permasalahan ini, penelitian ini bertujuan untuk melakukan simulasi pada daerah yang mengalami jatuh tegangan saat WPP berada di sistem Sulawesi Selatan. Metode sensitivitas dinamis disajikan dalam makalah ini. Dari hasil simulasi dan analisis, diperoleh lokasi load shedding di Makale, Palopo dan Latuppa dapat menstabilkan tegangan sistem namun menyebabkan area Poso berada dalam kondisi over voltage.

High Fidelity and Efficient Computations of Dynamic Loads for Multidisciplinary Design Optimization of Flexible Transport Aircraft

The current state-of-the-art design optimization of airframes is tightly wounded to its loads analyses as the process is usually conducted employing a deterministic set of critical load cases. The sheer number of scenarios required to estimate the critical loading conditions prevent these two processes from integrating, obstructing the development of a Multidisciplinary Design Optimization (MDO) framework. In this thesis, the problem of high fidelity and efficient estimation of critical dynamic aeroelastic loads is addressed, as a first step, towards the development of an integrated MDO platform for airframes at preliminary and detailed design stages. The method is based on the Kriging metamodeling technique along with the Latin Hypercube scheme for initial sampling and the expected improvement function for subsequent selection of sample points, known formally as the Efficient Global Optimization (EGO) algorithm. Furthermore, different inexpensive metrics, based on the concept of modal contribution factors, are investigated to serve as indicators to determine if a substantial change in the loads has occurred during the design optimization cycle, triggering the requirement for the re-exploration of the loads design space. A case study is presented to evaluate the performance of the proposed methodology versus a full factorial search. A reduction of 84% was achieved in the total time of execution employing the proposed methodology.
