中文摘要
电力系统谐波传播速度快,波及面广,对电网的安全稳定和经济运行构成极大威胁。现有成熟的并联型无源和有源滤波器无法滤除背景谐波,高次/超高次谐波滤除效果欠佳,滤波效果依赖于系统阻抗,容易引发负载电流放大现象,有源滤波器成本较高。电力系统亟需一种低成本高可靠性高低压系统通用的电能质量解决方案为中国能源互联网高品质电能质量保驾护航。为了增加系统谐波阻抗,抑制电压型谐波、背景谐波和高次谐波,减弱各种发生谐振的可能性,提高系统的稳定性,实现低成本高可靠性接入,本项目提出一种经济型高可靠性集成模块化即插即用串联型有源谐波隔离器的新思路。该有源谐波隔离器具有以下特点:经济性、高可靠性、实用性、通用性、集成性等。本项目将对该有源谐波隔离器的低成本控制策略、高可靠性接入方式、实用化措施、系统稳定性和参数优化等关键技术进行深入理论分析和工程化研究,实现该理论产业化,用具有自主知识产权的核心技术装备中国智能电网。
英文摘要
The fast propagation and wide spreading of power system harmonic have caused a great threat to the safety, stability and economic operation of power grid. To date, the widely used harmonic suppression methods parallel passive filter and traditional parallel active power filter, which are unable to suppress system background harmonics and are difficult to suppress the high order/super-high order harmonics and are with low cost performance, easily cause the load harmonic amplification. There is a pressing need for power quality solution with high reliability and cost performance to escort the high performance operation for China energy internet. In order to increase the system harmonic impedance, achieve better performance of suppress voltage-type harmonics, background harmonics and high order harmonics, and reduce the possibility of resonance, improve system stability and obtain high-reliability access, a novel plug-and-play integrated modular series active harmonic isolator with high reliability and cost performance is proposed in the project. The proposed active harmonic isolators is featured with the following characteristics: cost-effective, high reliability, practicability, universal property and module integration, and so on. In-depth theoretical analysis and engineering research on low cost control, the high-reliability access, practicability scheme, the system stability and parameter optimization will be conducted in this project so as to realize the industrialization of the theory and equip China smart grid with independent intellectual property rights.
