To improve the effect of existing inter-area oscillation control system in wide area network and multi-Agent system, the paper presents the control collaborative model of the inter-area oscillation based on multi-Agent and PMU for solving the problems presently such as centralized control and delay of wide-area power system in the control mode of t...
To solve the problem of the variancy of the wind power when wind farm connect with the power grid, a wind power predicting model of wind farm based on double ANNs is proposed in the paper. Wind velocity and wind direction on wind farm are the key of wind power predicting, and other circumstance conditions such as temperature, humidity, atmospheric...
In the paper, a matter-element model and correlation functions of running state is established based on fuzzy decision making by high voltage circuit breaker operating state evaluation index and its diversity and ambiguity. Based on matter-element theory, a circuit breaker model which can run the state judge's classic domain, node domain, and to be...
The grey theory is employed to establish the grey prediction-wind speed Weibull distribution model and calculate the Weibull distribution parameters according to the randomness and intermittence of the wind power output. The wind speed distribution of the wind farm and the effective wind power density are predicted accurately, the wind power and th...
To reconstruct accident succinctly and scientifically, four steps of vehicle-vehicle impact accident reconstruction based on Pc-Crash were discussed, including accident scene reconstruction, vehicle modeling, accident reconstruction, result analysis and verification. Three accident scene reconstruction methods were proposed. Key attention was paid...
A new concept has been put forward in the code of bills of quantities and valuation for construction works 2013, that is rate of variability for tender sum (RVFTS). This paper concentrates on the conception of the rate through the code and explores the application in combine with a practical project. Then a discussion about the influences of the bi...
Construction project management in China modeled after the foreigner countries. In China, construction project management staff usually in low level, low salary, high responsibility and distrusted by employers. Analyze the reason through the government department, employer, and the project management enterprise. Then suggest that the government sho...
Project investment is the most important factor in construction. Project-establishment, design, project bidding and construction phases are the basic stages in construction. According to different phases, scientific investment estimation method, cost engineers participating in design, realistic tender sum limit and strictly overall controlling are...
