项目摘要

With increasing opposition to building new transmission lines, transfer of bulk energy is going to be a major challenge in the UK and in many parts of Europe. Examples include the transmission link from the north of the UK to the load centres in the south and the corridor importing hydro power from north of Norway to the load centres near Oslo. It is therefore, absolutely critical that the existing power transmission assets are fully utilised by loading them much closer to their capacity. To ensure secure operation under such heavy loading, the dynamic performance of the system needs to be improved through appropriate control of voltage and power flow using the flexible ac transmission systems (FACTS) devices. It is often difficult to obtain accurate information about all the components (e.g. loads) of a power system which poses fundamental limitation on conventional model based control design. In the above context, this project aims at designing and validating a self-tuning control scheme for FACTS devices that rely solely on the measured signals and thereby, obviate the need for accurate system information. Such controllers are designed independent of the system operating condition and therefore, need no retuning with changes in system configuration. Use of more than one feedback signals from strategic locations, available though wide-area measurement systems (WAMS), can potentially improve the effectiveness of the FACTS controller. Hence, the control design needs to be formulated in a multi-variable framework. The performance of the controller would be validated in real-time through hardware-in-loop (HIL) simulation employing a test bench, emulating the behaviour of large power systems, and a commercial control simulator. The proposed project essentially integrates FACTS with WAMS and could potentially provide the developers and user of both these technologies a new edge.

随着对建立新输电线路的反对，在英国和欧洲许多地方，大量能源的转移将成为一个主要挑战。例子包括从英国北部到南部的负载中心的传输链接以及从挪威北部进口水力的走廊到奥斯陆附近的负载中心。因此，绝对至关重要的是，现有的电力传输资产可以通过更接近其容量来充分利用它们。为了确保在如此重载下的安全操作，需要使用灵活的交流传输系统（FACTS）设备来适当控制电压和功率流，从而改善系统的动态性能。通常很难获得有关电源系统的所有组件（例如负载）的准确信息，该系统对基于传统模型的控制设计产生了基本限制。在上述情况下，该项目旨在针对仅依赖于测量信号的事实设备设计和验证一个自我调整控制方案，从而消除了需要准确的系统信息。这样的控制器的设计独立于系统操作条件，因此，随着系统配置的变化，无需重新调整。使用来自战略位置的多个反馈信号（尽管广阔的测量系统（WAM））可有可能提高事实控制器的有效性。因此，控制设计需要在多变量框架中配制。控制器的性能将通过使用测试台，模拟大电源系统的行为和商业控制模拟器实时验证。拟议的项目实质上将事实与WAM集成在一起，并有可能为这两种技术的开发人员和用户提供新的优势。
