陕北浅埋煤层绿色保水开采技术研究

王家沟煤矿为陕北典型浅埋煤层矿井，地下煤炭资源开采有可能破坏萨拉乌苏组潜水含水层。为有效的控制导水裂隙发育，最大限度保护地表含水层，基于协调开采的原理，结合力学模型和相似材料模拟试验，对比研究了一次采全高和限高留煤柱两种开采方法导水裂隙发育规律。研究表明，一次采全高条件下导水裂隙呈间歇式变速发育最大高度94m，穿过含水层|限高留煤柱协调开采导水裂隙发育平缓，最大高度60m|关键层的稳定决定着含水层的稳定，限高留煤柱能够显著的控制协调关键层挠曲下沉，有效的抑制导水裂隙发育，实现含水层下绿色保水开采。     

Multiple models decentralized coordinated control of doubly fed induction generator

In this paper, a multiple model optimal tracking control (MOTC) design method for the double fed induction generator (DFIG) using correlative measured technique is proposed. The DFIG is represented by a third-order model, where electro-magnetic transients of stator are neglected. By using the correlative measured technique, the correlative measured matrix (CMM) of wind power system is obtained firstly. Then, a nonstandard state space equation of DFIG is obtained with the correlative measured vectors (CMVs), which reflect interactions between the DFIGs and grid. In order to cope with nonlinearities and continuous variation in the operating points, a multiple model design method is proposed in the discrete domain. The obtained control law, synthesized by using Bayesian probability, only depends on the local measured parameters. Hence, the MOTC can be regarded as a decentralized coordinated control, which can simplify the control structure and improve the transient stability of DFIG. To illustrate the effectiveness of the proposed MOTC strategy, simulations on a hybrid wind thermal power (HWTP) system are performed. The results show that the proposed MOTC strategy can provide acceptable performance throughout the whole operating region. Comparing to the conventional PID control, transient stability, damping, and fault ride-through capability of DFIG with the proposed MOTC design method have been improved effectively.     

One universal method of complex system reliability,maintainability, supportability,testability quotas design and trade-off based on improved flower pollination algorithm

For modern complex system, quality has become a serious and difficult problem that restricts the generation of combat effectiveness. Withal, based on domestic and foreign research and analysis, this paper puts forward a trade-off method for complex system reliability, maintainability, supportability, testability (RMST) design, which is suitable for product design stage. First, aiming at the uncertain problem of complex system constrained optimization, the good-point set population initialization, Deb feasibility comparison method and ε constraint method are integrated into the flower pollination algorithm, to construct the algorithm for RMST quotas design and trade-off. Second, taking the typical series-parallel repairable system as an example, one general model for complex system RMST quotas design and trade-off based on effectiveness is constructed. Finally, take an unmanned nuclear radiation detection system as a typical case, to verify its feasibility, advantages, and disadvantages.     

建（构）筑物下大条带协调式全采方法

建筑物下大条带协调式全采方法是先采用大条带跳采，采后地表产生较小的（约３０％）沉陷变形，而后仅用半数工作面即可联合开采剩余条带，最终实现全部开采，地表产生剩余的（７０％）沉陷变形量。此方法具有条带法开采和多工作面联合开采的优点，又同时克服了它们的某些缺点，明显地减少了地表沉陷变形值和采动影响次数，是保护地面建（构）筑物十分有效的开采措施。
