摘要： A missing stator slot wedge in an electrical machine can be detected by analysing a current spectrum of the machine in a high frequency area. A current spectrum is provided from a current measurement, and values of the current spectrum in the high frequency area used to determine whether a stator slot wedge is missing or not. The conclusion can be based on values of a relative current amplitude IdB or on presence of certain harmonics in the high frequency area.

摘要： This invention deals with an advanced Real-time Grid Monitoring System (RTGMS) suitable for both single-phase and three-phase electric power systems. This invention provides an essential signal processing block to be used as a part of complex systems either focused on supervising and diagnosing power systems or devoted to control power processors interacting with the grid. This invention is based on a new algorithm very suitable for real-time characterization of the grid variables under distorted and unbalanced grid conditions. The main characteristic of this invention is the usage of a frequency-locked loop, based on detecting the grid frequency, for synchronizing to the grid variables. It results in a very robust system response in relation to existing technique based on the phase-angle detection since grid frequency is much more stable variable than the grid voltage/current phase-angle, mainly during grid faults. Moreover, the algorithm supporting this invention is very efficient and can be implemented in regular industrial microprocessors. These features make the RTGMS object of this invention ideal to be applied in the control of distributed generation systems (DGS), flexible AC transmission systems (FACTS), power quality conditioners (PQC) and uninterruptible power supplies (UPS). In all these systems, the fast and precise real time detection of the voltage and/or current sequence components under grid fault conditions is a crucial matter.
摘要翻译：本发明涉及适用于单相和三相电力系统的先进的实时电网监控系统（RTGMS）。本发明提供了一种基本的信号处理模块，用作复杂系统的一部分，其重点在于监督和诊断电力系统，或专门用于控制与电网相互作用的功率处理器。本发明基于一种非常适合在失真和不平衡电网条件下对电网变量进行实时表征的新算法。本发明的主要特征是基于检测电网频率来使频率锁定环与网格变量同步的使用。由于电网频率比电网电压/电流相位角更为稳定，主要是在电网故障期间，因此相对于基于相位角检测的现有技术，可以获得非常强大的系统响应。此外，支持本发明的算法非常有效，并且可以在常规工业微处理器中实现。这些特征使得本发明的RTGMS对象理想地应用于分布式发电系统（DGS），灵活交流传输系统（FACTS），电力质量调节器（PQC）和不间断电源（UPS）的控制中。在所有这些系统中，在电网故障条件下电压和/或电流序列组件的快速和精确的实时检测是至关重要的。
