查询词典 grid current

This invention concerns a current control process for a feed-in voltage converter, wherein a detected flux-inducing current component and a detected torque-inducing currrent component of an actual currrent vector of a rotating field machine are each controlled for a flux-inducing current component set value and a torque-inducing current component set value of the rotating field machine. To that effect, a control set-value (DELTA u*sp, DELTA u*sq) is determined, dependent each time upon a determined current component control deviation. From these, current components of an actual current vector are formed each time by overlay of a formed pilot value (u*spvor, u*sqvor). This invention also concerns a device for carrying out this process.

本发明涉及一种用于馈入电压式变流器的电流调节方法，其中分别将所检测的一感应式电机的一实际电流向量（i s 的磁通感应电流分量和一转矩感应电流分量i sq ）调节至该感应式电机的一额定电流向量的一磁通感应分量额定值和一转矩感应电流分量额定值，在这种情况下，分别根据所检测的一电流分量调节偏差计算出一调节器调节量（△u * sp ，△u * sq ），由这两个调节器调节量分别通过叠加所形成的一预控制量（u * spvor ，u * sqvor ）形成一额定电压向量的电压分量（u * sp ，u * sq ），本发明还涉及一种用于实施该方法的装置。

The basic idea is to set a continuous solution of the region with a finite number of discrete points instead of a grid consisting of, these discrete points called grid nodes the solution of a continuous area on a given function of continuous variables used in the definition of discrete grid variable function approximation the original equation and boundary conditions in the micro-business operators to approximate differential, integral with the points and to approximate, so the original differential equations and boundary conditions are replaced by algebraic equations near Side, that is, finite difference equations , solve this equation group can get the original problem in discrete points on the approximate solution.

基本思想是把连续的定解区域用有限个离散点构成的网格来代替，这些离散点称作网格的节点；把连续定解区域上的连续变量的函数用在网格上定义的离散变量函数来近似；把原方程和定解条件中的微商用差商来近似，积分用积分和来近似，于是原微分方程和定解条件就近似地代之以代数方程组，即有限差分方程组，解此方程组就可以得到原问题在离散点上的近似解。
