摘　　要：特高压串补一次系统设备昂贵,结构复杂,故障类型多,其保护控制装置与传统的继电保护装置在硬件及软件需求上存在很大差异。为反映MOV及间隙放电等瞬变电流,串补保护控制系统对实时性要求非常高。在分析串补系统基本故障类型及对保护控制装置需求的基础上,提出了串补保护控制系统硬件及软件方案。硬件采用模块化设计,模拟量输入与处理、保护逻辑运算、通信及人机接口等硬件模块根据功能及性能需求独立设计,以达到最高效率及最好稳定性。软件分层分模块设计,底层软件由专业团队设计,复杂的应用层软件采用可视化编程环境实现,将各保护功能及算法模块化、可视化,降低了编程出错几率,提高了软件运行的稳定性。通过型式实验及数模仿真实验验证,所研制串补保护控制装置动作行为及性能符合相关行业标准要求。UHV series compensation system primary equipments are expensive, complex, and with a variety of fault types, so its protection and control devices are very different with conventional protection devices both in hardware and software requirements. To reflect the fast-changing currents such as MOV current and gap discharge current, the real-time requirement for the series compensation protection and control system is very high. Based on the analysis of the series compensation system protection and control devices’ function configuration and performance requirements, it proposes the hardware and software design solutions for the series compensation system protection and control device. From using modular design for the hardware, every module is independently designed based on its performance needs, such as analog input and processing, protection logic operations, communications and human-machine interface modules, it can achieve maximum efficiency and better stability. From using hierarchical modular design for the software, underlying software design and debugging by the professional design department, complicated application-layer software using visual programming environment, making the various protection functions and algorithms modular, visualization, it reduces the probability of programming mistakes and improves the operating stability of the device. Through the static and real-time digital simulation instrument （RTDS） simulation testing, the action behavior and performance of the series compensation protection and control device developed meets the design requirements and relevant industry standards.
