摘要 精准负荷控制是特高压交直流电网系统保护的重要组成部分,通过对负荷资源的分类、分级、分区域管理,实现由调度直接发令对分类用户可中断负荷的实时精准控制,能避免大量对变电所或线路进行整体拉闸,将电网故障的社会影响降到最低,提升大电网故障防御能力。为了保证精准负荷控制系统的稳定性和可靠性,在精准负荷控制系统投入使用前,需要对其进行充分的验证测试。本文针对精准负荷控制系统的特点,开发了一套模拟测试环境,该测试环境基于实际的软硬件架构,针对内部通信特点,研究测试方法,定制测试用例驱动,能够模拟满负荷运行下的各种运行工况,全面验证和考核精准负荷控制系统的功能性能,从而保证精准负荷控制系统的稳定性和可靠性。该测试方法已经在精准负荷控制系统的研发测试过程中得到了充分的应用。

Abstract:Precision load control was considered an integral part of UHV (ultra-high voltage) AC/DC power grid system protection. Real-time precise control which the dispatcher can send commend directly to interruptible load for user classification could be done via classification, hierarchical and sub-regional management of load resources. This approach has the virtue of not requiring switch off a large number of substations or lines which can minimize the social impact due to grid failures and improve defense capabilities for bulk power systems. In order to guarantee the stability and reliability of precision load control, it is essential to be validated through adequate testing before its operation. Responding to the characteristics of precision load control system, this paper has developed a set of simulation test environment which can simulation various operation conditions running at full capacity and verified its effectiveness comprehensively through researched test methods and customized test case drivers based on actual hardware and software components, the characteristics of interior communication as well, thus ensuring the stability and reliability of precision load control system.This test metrology has been fully applied in the field of developing and testing process of precision load control system.
