seismic interaction in electrical Substation Equipment connected by non linear rigid bus conductors
Earthquake Engineering & Structural Dynamics, 2007Co-Authors: Junho Song, Armen Der Kiureghian, Jerome L SackmanAbstract:An important element within the power transmission lifeline is the electrical Substation that typically consists of a complex set of Equipment items interconnected through conductor buses or cables. If the connections are not sufficiently flexible, significant dynamic interaction may occur between the connected Equipment items during a seismic event, which may result in damage and loss of the Equipment. This paper investigates the interaction effect between electrical Substation Equipment items connected by non-linear rigid bus conductors. The Equipment items are modelled as single-degree-of-freedom oscillators by use of appropriate shape functions. The hysteretic behaviours of rigid bus connectors are described by differential equation models fitted to experimental data. An efficient non-linear random vibration method is used to quantify the seismic interaction effect of the connected Equipment items. Based on the developed analytical models and method, the effect of interaction in the connected Equipment system is investigated through extensive parametric studies. The results lead to practical charts and guidelines for the seismic design of interconnected electrical Substation Equipment. Copyright © 2006 John Wiley & Sons, Ltd.

Seismic interaction in linearly connected electrical Substation Equipment
Earthquake Engineering & Structural Dynamics, 2001Co-Authors: Armen Der Kiureghian, Jerome L Sackman, K‐j. HongAbstract:An electrical Substation consists of a complex set of Equipment items that are interconnected through conductor buses or cables. If the connections are not sufficiently flexible, significant dynamic interaction may occur between the connected Equipment items during a seismic excitation. This interaction is believed to be responsible for some of the observed Substation Equipment damage in recent earthquakes. This paper investigates the interaction between two Equipment items connected by a linear spring-dashpot or spring-dashpot-mass element representing a conductor bus. It is found that the interaction between the two Equipment items may significantly amplify the response of the higher-frequency Equipment item. The influences of various key parameters on the interaction effect are quantified. Means for reducing the adverse interaction effect are described. Copyright © 2001 John Wiley & Sons, Ltd.

failure rate prediction model of Substation Equipment based on weibull distribution and time series analysis
IEEE Access, 2019Co-Authors: Jingjing WangAbstract:The failure rate is an important indicator to assess the reliability of Substation Equipment, and the failure rate prediction is an effective way to master the operation status of Substation Equipment. According to the characteristics of failure rate data, such as failure period segmentation and stochastic variation, this paper proposes a combined prediction method by the data decomposition of failure rate time series and the segmentation theory of failure periods and then establishes a new failure rate prediction model of the Substation Equipment based on the Weibull distribution and time series analysis. Compared with the traditional Weibull distribution function model which cannot describe the stochastic variation of failure rate data and cannot identify the failure period automatically, the proposed model in this paper uses the minimum sum algorithm of residual squares obtained by the Weibull distribution to accurately identify the demarcation point between different failure periods and then establishes the autoregressive moving average (ARMA) model to achieve combined prediction. Finally, the effectiveness of the proposed model is verified by the engineering example and comparison with the traditional failure rate prediction methods.
