This book is based on a Ph.D. research that has been conducted at the Delft University of Technology in the Netherlands in collaboration with Dutch Electricity & Gas Distribution Network Operator, Stedin. This book was written as a result of wider interest that was shown by different industry groups on this topic after its public defence. This inspired the author to modify and publish a practical version of the research for a greater international audience. Therefore, the content of this book is intended for a double audience, on the one hand for those interested in the organisational and management aspects of maintenance.

n present power system, the engineers face variety of challenges in planning, construction and operation. In some of the problems, the engineers need to use managerial talents. In system design or upgrading the entire system into automatic control instead of slow response of human operator, the engineers need to exercise more technical knowledge and experience. It is principally the engi- neer’s ability to achieve the success in all respect and provide the reliable and uninterrupted service to the customers. This chapter covers some important areas of the traditional power system that helps engineers to overcome the challenges. It emphasizes the characteristics of the various components of a power system such as generation, transmission, Distribution, protection and SCADA system. During normal operating conditions and disturbances, the acquired knowledge will pro- vide the engineers the ability to analyse the performance of the complex system and execute future improvement

Modern power systems involve large amount of investment. An electric power system comprises of generation, transmission, and Distribution of electric energy. Growth of power systems has led to very complex networks extended across large areas. In such situations, the proper functioning of a modern power system is heavily dependent upon the healthy operation of the transmission lines within it. Transmission lines are used to transmit a huge amount of power over a long distance. But as these lines are located in the open atmosphere, they are highly affected by different types of abnormal conditions or faults.

配电网中,各种配电终端的电流、电压、有功功率及无功功率等模拟量的采集是配电网自动化的重要环节。这些模拟量的采集也是各种仪器和家用电器的必要功能。因此,设计了基于嵌入式STM32F103单片机的交流电压、交流电流及有功功率的采集系统,通过电压互感器TV1005M和电流互感器TA1005M分别检测交流电压和交流电流值;屏幕或者手机APP和WiFi模块互联后,可以实时显示交流电压、交流电流、功率及电量值;通过设定阈值功率,可以实现对电流的监控和对电路的保护。In the Distribution network,the collection of analog,such as current,voltage,active power,and reactive power at various Distribution terminals is a very important part of Distribution network automation. These analog acquisitions are also for various instruments and household appliances. Very important technology. Therefore,an AC voltage,AC current and active power acquisition system based on embedded STM32 F103 machine is designed,and AC voltage and AC current values are detected by voltage transformer TV1005 M and current Transformer TA1005 M respectively;After the screen or mobile phone APP and WiFi modules are interconnected,AC voltage,AC current,power,and power values can be displayed in real time;By setting the threshold power,the current can be monitored and the circuit can be protected.
