Design and implementation of an integrated switched-oscillator impulse generator with application in wireless passive electric field sensors

近几十年来，电力需求的增长促使高压电器满负荷运行，而电力系统公用事业公司则希望提供高质量和可靠的电力。为了避免因设备故障和停电造成的停电和干扰，在线、分布式、低成本的状态监测、诊断和保护在现代电力系统中至关重要。无源无线传感器是一种新兴的设备，用来增强现有的状态监测方法。这些传感器不需要内部电源。它们被外部能量来源激活和审问。使用询问器将信号传输到传感器，并分析从传感器反射的包含由传感器收集的信息的接收信号。 这个项目的目标是设计、制造和测试一种开关振荡器，它将显著改善研究人员目前使用的审讯系统的性能。新型无源无线传感器(也是由同一研究团队开发的)和改进的询问系统的可用性将增强电力系统公用事业公司监测其高压设备和系统状况的能力。

The increasing demand for electric power over the last decades has urged the high voltage apparatus to operate at full load while the power system utilities are expected to provide high quality and reliable electric power. In order to avoid power outages and disturbances caused by equipment failures and outages, online, distributed, and low-cost condition monitoring, diagnostics, and protection are crucial in modern power systems. Passive, wireless sensors are emerging devices to enhance the existing condition-monitoring methods. These sensors do not require an internal power source. They are activated and interrogated by an external source of energy. Using an interrogator, a signal is transmitted to the sensor and the received signal reflected from the sensor is analyzed that contains information collected by the sensor. The objective of this project is to design, build, and test a switched oscillator that will significantly improve the performance of the interrogation system currently used by the researchers. Availability of the novel, passive, wireless sensors (that are also developed by the same research team) and the improved interrogation system will enhance power system utilities ability to monitor the condition of their high voltage equipment and systems.
