Authors: Bian Siyu , Zhuo Jingchao , Zhu Liming 
Published: September 2020

Abstract
In this paper, a model based on CEEMDAN-ARIMA is proposed to predict the strain monitoring data for bridge SHM. In view of the problem that the classical time series theory cannot predict the modal overlap-ping data effectively, the CEEMDAN method was used to decompose the strain monitoring data for the bridge SHM. To deal with the large number of components after using CEEMDAN, the PE method (permutation entropy) was used to generate a series of new data sequences according to the degree of randomness. Finally, each new data sequence was predicted and the final prediction is obtained by ARIMA model. The method was used to predict the SHM strain data of a cable-stayed bridge in Shanghai. The results show that the proposed combination method is more accurate than the classical time series theory and is promising for engineering applications.

Published: September 2020

Abstract
The research on wind resistance monitoring technology of typical cement pole-line structure in 10kv transmission line is carried out in view of the fact that the transmission lines in the coastal areas of South China are often threatened by typhoons. Firstly, a wind-resistant monitoring system for pole-line structures is established. Secondly, the method to determine the early warning value in the monitoring system is proposed and the whole finite element model of the pole-line is established. Then, the wind speed is transformed into wind load to determine the early warning value of wind speed according to the wind-pole fluid-solid coupling model. Finally, the correctness of the wind-resistant monitoring technology of the pole-line structure is verified by the results monitored by practical engineering. The research shows that the wind load on the surface of the conductor is non-uniform, which can be accurately calculated through the wind-pole fluid-solid coupling model; The structural response obtained by the whole finite element model of the pole-line structure can accurately reflect the actual stress state, which can be used to determine the early warning value of wind speed; The proposed wind-resistant monitoring system in transmission lines has been verified by practical projects and can be popularized.

Published: September 2020

Abstract
The Beishan area of Gansu, China, is an arid desert area, and the surface rocks are well-exposed, creating excellent conditions for drone remote sensing geological mapping experiments. The magmatic rocks and metamorphic rocks in the Beishan area are widely exposed, and a large number of basic and acidic dykes have developed. The formation and distribution of gold deposits are closely related to the dykes. In order to explore the development rules of dykes in this area, a 20km2; area in the Changliushui area of Beishan was selected as the target, and a set of methods for studying the dyke swarm using drones was formed and applied: Images were collected and high-resolution orthophotos and three-dimensional models were synthesized, combined with ground work, and finally remote sensing geological interpretation was performed, to obtain high-precision geological maps. Based on this, the dykes were identified in detail and divided into four phases. The strikes and dips information of the dykes was extracted, and it could be concluded that the dominance of the strikes of the dykes in the target area is NEE, and the inclination is nearly upright, while the length and thickness of dykes obey a skewed distribution. The application of the method not only provides more geological information, but also provides clues for the tectonic evolution and formation mechanisms of dyke swarms, indicates the prospecting direction of future gold deposits.

Authors: Jia Yajun , Chen Cunli 
Published: September 2020

Abstract
This paper analyses the water content of landslide loess in Tianshui City, Gansu Province. Through triaxial cyclic loading and unloading rheological tests, the creep curves and water content forms of landslide loess under different confining pressures are obtained, and their rheological constitutive model for analysis. The rheological constitutive model test under triaxial conditions shows that under low and high stress conditions, the creep strain rate decreases with time, which is manifested as decelerating creep; only under high stress conditions, creep strain The rate undergoes a process of decreasing first, then stabilizing, and finally increasing, corresponding to the three stages of deceleration creep, constant velocity creep and acceleration creep. The specimen will produce a certain instantaneous elastic deformation under different stresses. The rheology of loess has a nonlinear characteristic. The stress-strain iso-curve gradually shifts toward the strain axis as the stress level increases, and the degree of nonlinearity increases as the stress increases.
Analysis on the Variation Trend of Evaporation and Precipitation in Xiaolangdi Reservoir
Authors: Ma Ziru 
Published: September 2020

Abstract
Based on the monthly evaporation and precipitation data from 1982 to 2013 of 13 meteorological stations in and around the Xiaolangdi Reservoir, the linear tendency estimation method, cumulative anomaly, M-K mutation detection method and ARIMA model are used to study and predict the changing characteristics of evaporation and precipitation. The results show that the annual evaporation and precipitation in the reservoir area both show a downward trend. The evaporation has an abrupt decline in 2001, and the precipitation decreases suddenly in 2003 and 2011. After impoundment, the annual evaporation volume changed from the upward trend to a weak downward trend, and the downward trend of annual precipitation is weakened. The impact of impoundment on evaporation and precipitation is limited, and the impact intensity decreases with increasing distance from the reservoir. The reservoir area’s evaporation and precipitation have significant seasonal variation characteristics, and the future evaporation will show a slight downward trend, while the precipitation will show a slight upward trend.

Published: September 2020

Abstract
In order to discuss the application of energy storage system in power energy control, in this study, the energy storage system in small wind power generation system is taken as the research object, and the converter mathematical model in the energy storage system is built. Meanwhile, in the control state of grid-connected operation, the energy storage system is analyzed and a Power Systems Computer Aided Design / Electromagnetic Transients including Direct Current (PSCAD/EMTDC) simulation model based on Power Quality (PQ) control and Space Vector Pulse Width Modulation (SVPWM) mode is built. And when Insulated Gate Bipolar Transistor (IGBT) fails on the upper bridge arm of A-phase Alternating Current (AC) converter in the energy storage system, the changes of AC voltage, AC current, active power, and reactive power in the system and simulated. The results show that the simulation model of energy storage system established by PSCAD/EMTDC is feasible under the PQ control of grid-connected operation. In addition, fault analysis shows that the current conduction of A phase is delayed in the negative half wave, and there is a positive Direct Current (DC) bias, but the distortion of current of B phase and C phase is not significant. And the active power and reactive power remain within the set reference range. Therefore, it is possible to determine the failure of the converter IGBT of the energy storage system by whether or not the three-phase current on the AC side of the energy storage system has a DC offset. This study aims to provide theoretical basis for the follow-up fault diagnosis and system protection of the energy storage system.

Published: September 2020

Abstract
Accurate demand forecasting is very important for power system operation and planning. In order to forecast energy demand more accurately, a short-term power load forecasting model based on Bayesian neural network is proposed. Firstly, Pearson coefficient is used to analyze the influence of distributed energy on the load of the distribution network, and Bayesian neural network (BNN) is used to make predictions. Then, particle swarm optimization (PSO) is used to optimize the weights and thresholds of the neural network in order to obtain the best prediction effect. The experimental results show that the Pearson coefficient can quantitatively analyze the impact of distributed energy. The prediction accuracy of BNN-PSO based prediction model is significantly higher than that of other conventional methods, and the proposed prediction model has higher prediction accuracy.
