Preface

Power system consists of power generation, transmission, transformation, distribution and consumption. The power system will convert other energy in nature from power generation device to electric energy, and then through the links of power transformation, transmission and distribution, the electric energy will be transformed into the power resources to be used by the load point. Electrical equipment mainly refers to the motor, transformer, circuit breaker, relay protection device and other equipment in the power system. In order to maintain the continuous supply of electric power, the primary condition is to do a good job in fault diagnosis and maintenance of electrical equipment.
With the further development of power technology, the power supply performance and quality of power equipment have also obtained a qualitative leap

  Power System Engineering and Electrical Equipment systematically introduces the planning of power system, the main performance of power system security, stability and power system monitoring and control, and introduces the main electrical equipment in power system, including motor, transformer and relay protection device. In the process of power system operation, it is easy to be affected by external factors. In order to ensure the security and stability of power system operation, it is necessary to improve the application efficiency of electrical equipment in power system. The normal operation of power system needs healthy and stable power equipment, and substation maintenance work is the basis of power equipment health and stability

前 言

电力系统由发电、输电、变电、配电和用电等环节组成的电能生产与消费系统。电力系统会将自然界中的其他能源由发电装置转化为电能，再经过变电输电配电等环节将电能转化为负荷点要用电力资源。电气设备主要是指电力系统中的电机、变压器、断路器、继电保护装置等设备。为了保持电力的持续供应，做好电气设备故障诊断和检修工作是首要条件。随着电力技术的进一步发展，电力设备的供电性能和质量等也获得了质的飞跃。
      《电力系统工程与电气设备》这本书系统介绍了电力系统的规划、电力系统的主要性能——安全性、稳定性以及电力系统的监视与控制，同时介绍了电力系统中主要的电气设备，包括电机、变压器、继电保护装置。电力系统在运行的过程中很容易受到外界因素的影响，想要保证电力系统运行的安全性和稳定性，就要提高电力系统中电气设备应用效率。电力系统正常运行需要健康稳定的电力设备，而变电检修工作是电力设备健康稳定的基础。
