技术领域Technical field
本申请涉及柔性直流输电领域，例如涉及一种柔性直流阀基控制设备的闭环测试装置及测试方法。This application relates to the field of flexible direct current transmission, for example, to a closed loop test device and test method of flexible direct current valve base control equipment.
背景技术Background technique
基于模块化多电平换流器(Modular Multilevel Converter，MMC)的柔性直流输电被誉为继交流输电、常规直流输电之后的第三代输电技术。与前两代输电技术相比，其最大的提升是能够在传输能量的同时，还能够灵活调节电力***的电压，提高输电***的安全稳定性，在可再生能源发电并网、大型城市/重要负荷供电、电网互联、孤岛/钻井平台供电等领域具有很好的应用前景。阀基控制设备(Valve Based Control，VBC)是柔性直流输电工程中的重要一环，其测试方法研究具有重要意义。Flexible DC transmission based on Modular Multilevel Converter (MMC) is known as the third generation of power transmission technology after AC power transmission and conventional DC power transmission. Compared with the previous two generations of transmission technology, its biggest improvement is the ability to flexibly adjust the voltage of the power system while transmitting energy, improve the safety and stability of the transmission system, and connect renewable energy power generation to the grid, large cities/important Load power supply, grid interconnection, island/drilling platform power supply and other fields have good application prospects. Valve-Based Control (VBC) is an important part of the flexible HVDC project, and its test method research is of great significance.
柔性直流输电阀基控制设备的功能设计基本一致，硬件架构稍有区别，VBC主要作为换流阀(VALVE，由多个子模块串联而成)与极控制保护设备(Pole Control and Protection，PCP)的中间枢纽，承担通信编/解码、电平调制、桥臂环流抑制、子模块电容电压平衡控制、换流阀和子模块级故障保护、设备自检、换流阀状态监视等功能。The functional design of flexible DC transmission valve-based control equipment is basically the same, and the hardware architecture is slightly different. VBC is mainly used as a converter valve (VALVE, which is composed of multiple sub-modules in series) and pole control and protection equipment (Pole Control and Protection, PCP). The intermediate hub is responsible for communication encoding/decoding, level modulation, bridge arm circulation suppression, sub-module capacitor voltage balance control, converter valve and sub-module level fault protection, equipment self-checking, converter valve status monitoring and other functions.
根据设计架构的不同，多个厂家提出了不同的VBC测试方案，主流的测试方案包括两种，但均存在一定缺陷：According to different design architectures, many manufacturers have proposed different VBC test schemes. There are two mainstream test schemes, but they all have certain defects:
依据“惯性等效原则”设计动态模拟仿真平台用于阀控测试，可全面测试阀控接口，但不便于进行***级操作及***级、定量化故障测试，而且动态模拟仿真平台与VBC基本分别组柜，对所需光纤的长度和数量均有较高要求，实验平台搭建工作量较大、成本较高。According to the "inertial equivalent principle", the dynamic simulation simulation platform is designed for valve control testing, which can fully test the valve control interface, but it is inconvenient for system-level operation and system-level, quantitative fault testing, and the dynamic simulation simulation platform is basically different from VBC Assembling cabinets has high requirements on the length and quantity of optical fibers required, and the construction of the experimental platform requires a lot of work and high costs.
实时半实物硬件在环(hardware in loop，HIL)测试仅仅讨论柔性直流***启动、顺控解锁、短路故障等***级故障测试，换流阀子模块故障类型单一；或者设计的实时仿真***与VBC的接口设备仅充当通信转换工具，不具备全面、定量验证阀控接口功能条件，VBC测试项目不够全面，参与测试的VBC程序甚至是将工程程序简化或裁减过的，测试结论不够权威。The real-time hardware-in-loop (HIL) test only discusses system-level fault tests such as flexible DC system startup, sequence unlocking, short-circuit faults, etc. The converter valve submodule has a single fault type; or the designed real-time simulation system and VBC The interface device only serves as a communication conversion tool, and does not have the conditions for comprehensive and quantitative verification of valve control interface functions. The VBC test items are not comprehensive enough. The VBC procedures involved in the test are even simplified or reduced. The test conclusions are not authoritative.
