摘要： In steady-state voltage stability analysis, as load increases toward a maximum, conventional Newton-Raphson power flow Jacobian matrix becomes increasingly ill-conditioned so power flow fails to converge before reaching maximum loading. A method to directly eliminate this singularity reformulates the power flow problem by introducing an AQ bus with specified bus angle and reactive power consumption of a load bus. For steady-state voltage stability analysis, the angle separation between the swing bus and AQ bus can be varied to control power transfer to the load, rather than specifying the load power itself. For an AQ bus, the power flow formulation is only made up of a reactive power equation, thus reducing the size of the Jacobian matrix by one. This reduced Jacobian matrix is nonsingular at the critical voltage point, eliminating a major difficulty in voltage stability analysis for power system operations.
摘要翻译：在稳态电压稳定性分析中，随着负载向最大值的增加，传统的牛顿 - 拉夫逊电力雅可比矩阵变得越来越不合理，因此功率流在达到最大负载之前不会收敛。通过引入具有指定总线角度和负载总线无功功率的AQ总线，直接消除该奇异性的方法重新制定了功率流量问题。对于稳态电压稳定性分析，可以改变摆幅母线与AQ母线之间的角度间隔，以控制对负载的功率传输，而不是指定负载功率本身。对于AQ总线，功率流量公式仅由无功功率方程组成，从而将雅可比矩阵的大小减小1。这种减少的雅可比矩阵在临界电压点是非奇异的，消除了电力系统操作的电压稳定性分析的主要困难。

摘要： A communication system includes functional modules, wherein at least one functional module includes a processing unit and at least one functional module includes a controllable device. The modules are powered by an alternating voltage at a frequency and are electrically associated by a power bus and a communication bus. The processing unit provides a communication signal to the communication bus for interaction between the functional modules through a plurality of sets of high frequency pulses arranged to repeat at a predetermined repetition frequency substantially greater than the frequency of the voltage, and each set of high frequency pulses forms an information pulse corresponding to at least one bit of a communication protocol. Filters are disposed between an electric energy power supply and the functional modules for permitting the passage only of frequency components of an electric signal greater than the voltage frequency of the electric energy power supply.

The IED may determine a residual flux value of the transformer based at least in part on the voltage measurements, the voltage measurement matrix and the delta connection compensating angle. The IED may send a signal to a circuit breaker of the transformer to connect the transformer to the power system based at least in part on the system voltage and residual flux value.
