This work presents an experimental study of the unbalance compensation caused by the high speed railway substations in the high-voltage power grid with a shunt voltage source inverter based STATCOM. This experimental study is realized on a reduced scale prototype. The Control of inverter is implemented in a DSP card. The practical results presented in this paper are shown the performance of unbalance compensation by VSI_STATCOM in static and dynamic regime.

Prediction on red clay foundation settlement was put forward, using hyperbola method, exponential curve method and Hushino method, based on field data. Furthermore, Verhulst model, Gompertz model, Logistic model and Weibull curve were adopted in foundation settlement prediction. Subsequently, variable weight combination method and optimized combination model was studied to get more accurate prediction results. Finally, red clay foundation prediction of high speed railway was proposed.

Allowable Temperature

Due to the usage of high-strength concrete, excessive hydration heat is generated in the whole span box girder of high-speed railway. The maximum allowable temperature should not exceed 60°C according to the Technical Guide on Railway Bridge Construction of Passenger Dedicated Line. However, according to the field measurement and simulation to the maximum temperature of box girder concrete, we find that the maximum hydration temperature of concrete is generally more than 60°C which is the limited value of the specification. The research results show that the limited value of maximum hydration temperature for box girder concrete can be relaxed to 65°C.
