After flow and transient stability calculating of the 330kV grid, we got the over-load and hazard lines set. Then we gained the redundant network needed to be built according to the increasing power supply and load in 2010. Adopting regradation step-by-step algorithm by which we can improve the calculation efficiency , we compared the validity of every line, deleted lines with low validity until no redundant line is in the network. At last we got the target network framework adopting the improved ant colony algorithm. Flow distribution, construction investment assessment and target framework of Gansu long-term planning all be considered, from the viewpoint of to be economic and reliability the feasibility of the improved ant colony algorithm is discussed.

在对2006年该网架结构进行了潮流计算与暂态稳定计算分析后，得出了系统的过负荷与危险线路集，并针对2010年新增的电源和负荷点确定了冗余的待建网架，然后利用逐步倒推法比较各待选线路在系统中的有效性，逐步去除有效性低的线路，直到网络中没有冗余线路为止，以此来以提高优化算法的计算效率，最后利用改进后的蚁群算法确定优化后的目标网架结构，并从潮流分布、建设投资估算等方面与甘肃电网远期规划中确定的目标网架进行了比较，从可靠性和经济性角度论证了改进蚁群算法在网架优化中的可行性。

The calculation results shows that ,(1) when the rotor rotates at the working speed, a local regurgitant whirlpool that is rightabout to the rotor"s rotating direction appears in the classifying region, which makes the separated granules come back to the outside of the classification district and influences the classification efficiency of the turbine classifier;(2) in the condition of a low rotating speed of turbo rotor, ultrafine particles can follow the gas phase by and large, but when the rotating speed increases, a phenomenon of velocity slippage between two phases appears evidently;(3) A operating parameter, air flow rate is so important that can directly influence the stability of flow field in classifying chamber, the bigger the air flowrate is , the steadier the flow field is;(4) Compared with straight blades, the new shape of blades with backward crooked elbow are helpful to improve the stability of flow field and form whole stream easily, also beneficial to advance the classification accuracy and classification efficiency;(5) The motion trace of particles are very complicated when the turbo rotor rotates at a high speed, the constant bounce of the particles appear between the blades and the coarse particles are even bounce back from the inlet, only the finer can pass through the classification area from the oulet;(6) Along with the increase of the rotor"s rotating speed, radiah axial and tangential velocity all begain to fluctuate repetitively like sine-wave, the smaller the particles are, the more violently they fluctuates.

数值模拟结果表明，(1)在涡轮达到工作转速时，在分级区域形成了一个与涡轮旋转方向相反的局部回流涡，它使得分离出来的细粒重又被带回分级轮外边缘，从而严重影响分级机的分级效率；(2)粉尘粒子在涡轮低速运动情况下，基本上能跟随气体运动，但随着转速加大，两相之间出现了明显的速度滑移现象；(3)分级机工作时的风量也是一个比较重要的操作参数，它可以直接影响到分级机内腔流场的稳定性，风量越大，流场越稳定；(4)同直叶片形状相比较，带后弯导板的叶片，有利于改善流场的稳定性，流场容易形成整体流，对提高分级效率和分级精度都非常有利；(5)粒子轨迹线在涡轮转速较高时十分复杂，有的出现了反复的弹跳现象，大颗粒不能通过分级区域而从进口返流了，只有细小的颗粒才从出口处流出；(6)涡轮转速加大时，粒子的径向、轴向和切向速率出现了明显的类似于正弦波的脉动现象，颗粒越小，脉动程度越为剧烈。
