摘要：
In recent years, in order to save line corridors and reduce the scope of demolition, some new transmission modes for high voltage AC and DC power transmission line are proposed. According to the characteristics of the parallel transmission line, this paper studies the distribution characteristics of the electric field intensity of multi circuit parallel transmission lines and the single circuit transmission line. Comparing and analyzing the simulation results of the electric field strength, the safety measures for live working of similar to 500kV DC transmission line with multi circuit parallel transmission lines is put forward. That is the electric field protective equipment and measures used in the live line work of the +/- 800kV HVDC single circuit line can meet the requirements of the live operation of the +/- 500kV HVDC multi-circuit transmission line.

摘要：
Double-joint strain insulator fittings are the main equipment substations. It is great significance for reducing its maximum electric field strength to avoid corona noise and to improve substation electromagnetic environment. Firstly double-joint strain insulator string fittings simulation model is given by use of ansys 14.0, and the electric field is simulated and calculated according to the actual installation location of the related equipment. The construction for double-joint strain insulator string fittings is optimized to reduce the electric field value on basis of studying on the simulation significantly higher electric field points. The simulation results show increasing the number of equalizing shielding ring, for reducing the electric field strength of double-joint strain insulator string fittings, is more effective than increasing the diameter of equalizing shielding ring.

The construction for single-joint strain insulator string fittings is optimized to reduce the electric field value on the basis of studying the simulation significantly higher electric field points.

摘要：
This paper introduced a new modular multi-level converter (MMC), which could enhance the voltage and power level by sub-converter modules in series and was easy to extend to any level of output. Its structure and working mechanism were described. By analyzing the energy transfer performance of STATCOM based on MMC working conditions in the unbalance compensation, this paper studied compensation control theory in unbalanced complex conditions. To obtain compensation control response speed faster and better compensation effect, a comprehensive compensation control strategy was proposed based on direct current control mode. The simulation results show the strategy has a better tracking precision and response speed for the unbalance compensation current.
摘要：
This paper introduced a new modular multi-level converter (MMC), which could enhance the voltage and power level by sub-converter modules in series and was easy to extend to any level of output. Its structure and working mechanism were described. By analyzing the higher harmonic components circulation generated by the inconsistencies in the three-phase upper and lower arm voltage, a loop control strategy is proposed for the suppression of the circulation in the arms of the M-STATCOM. Simulation results verify the effect of the controller.
摘要：
The type selection for agricultural machinery generally depends on the selector's experiences at the present time. It exist some subjectivity and one-sidedness unavoidably. On the basis of the characteristics of complexity and the uncertainty of optimal selection for agricultural machinery, grey relational analysis model in agricultural machinery multi-type selection application has been put forward in this paper. The index system of influencing agricultural machinery type selection is determined. Application model and procedures of the grey relational analysis method are introduced. According to the degree how close it is with the ideal dot, the optimal type is easy to be selected out. Through the optimization analysis type selection for the agricultural transporter, it is proved that the optimal type selection for agricultural machinery based on grey relational analysis has the strong recognition judgment ability. It is convenient, quantitative, and strict. It provided a new method and a possible new way for evaluation of agricultural machinery type selecting.
