eAssessment The application of multiterminal (MT), high-voltage dc (HVdc) (MTdc) grid technology requires test procedures for the operation and implementation of the protection solutions. The test procedures are usually derived from experience and from extensive measurement data, which, at present, are still not widely available. Based on a hardware-inthe- loop (HIL) method, advanced dc protection testing strategies, utilizing existing experience for ac grids and requirements for MTdc grids, may overcome this gap.

多端高压直流电网的保护测试：程序和

电子评估 多端 (MT)、高压直流 (HVdc) (MTdc) 电网技术的应用需要针对保护解决方案的运行和实施进行测试程序。测试程序通常来自经验和广泛的测量数据，这些数据目前仍未广泛使用。基于硬件在环 (HIL) 方法，先进的直流保护测试策略，利用交流电网的现有经验和 MTdc 电网的要求，可以克服这一差距。
