The method employs characteristic values such as hinge node voltage at dividing place between the large district grid and the provincial grid and tie line reactive power and so on as a coordinated variable of wattless control of the large district grid and the provincial grid, and real-timely calculates an optimal set value of the coordinated variable in the large district grid which is sent down to the provincial grid via wide area communication. In the coordinated control of the provincial grid, the method can not only realize the control object of original grid, but can also realtimely track the optimal set value of the coordinated variable given by the large district grid.
本方法选择大区电网与省级电网分界处枢纽节点电压和联络线无功等特征量作为大区电网与省级电网无功控制的协调变量,通过大区电网的无功优化,实时计算出大区电网中协调变量的最优设定值,该设定值通过广域通信下发到省级电网,在省级电网的协调控制中,除了满足本级电网的控制目标外,还实时跟踪由大区电网给出的协调变量的最优设定值。

An adaptive grid scheme controlling cell area is used to generated grids in the divergent section of symmetric annular nozzle, and the generated grids are used in the flowfield calculation through the uncoupled way. The elliptic equations are used to generate grids in three dimensional regions of FDN divergent section, the source terms used in the equations employ a mathematical form which is independent of the boundary shape and of the boundary grid point distribution, the free parameters contained in the source terms are determined by the two restraint conditions, the intersection angle of transverse grid lines with boundaries and the local curvature of the transverse grid lines at the boundaries, and the interior grid distribution controlled directly by the grid point distribution assigned on the boundaries is realized, it makes the grid more clustering near the nozzle wall. For the generated grids in the whole computational regions have a good smoothness and orthogonality, the accuracy of calculation in the flowfield is ensured.
对轴对称的环形喷管采用控制网格面积的自适应网格方法对扩散段部分进行了网格生成,并通过非耦合方式应用于喷管的流场计算中;对强制偏流喷管扩散段内的三维区域采用椭圆型方程进行网格生成,方程中的源项采用了与边界形状和边界网格点分布无关的数学形式,源项内的自由参数由横向网格线与边界的交角及横向网格线在边界处的局部曲率两个约束条件来确定,实现了由边界上的网格分布直接控制内部的网格点,使壁面附近具有较密集的网格,并且在整个计算区域内的网格都具有良好的光滑性和正交性,从而保证了流场计算的准确性。
