在“碳达峰∙碳中和”目标下,电化学储能电站快速发展,但受到变流器控制策略的影响,电化学储能电站的故障特性与传统同步电源存在较大差异。同时,储能电站具有充电及放电两种运行模式,这使得其故障特征与风光等新能源不同。因此,电化学储能电站的接入将对配电网功率方向元件产生严重影响。首先,研究了电化学储能电站的故障特性,并在此基础上分析了电化学储能电站在充放电运行模式下的故障特性对电网保护方向元件的影响机理;然后,提出了基于电流选跳原理的故障识别方法,可有效消除电化学储能电站接入对功率方向元件造成的误判影响;最后,基于PSCAD/EMTDC仿真平台进行验证。结果表明,储能电站充电时短路电流与电压的相位差变化导致储能电站侧功率方向元件错误动作,而文中所提保护方案不受储能电站充电模式的影响,可以快速、正确地识别故障位置。
Under the goal of “carbon emission peak and carbon neutrality”
the electrochemical energy storage power stations are rapidly developing. However
due to the influence of converter control strategies
the fault characteristics of electrochemical energy storage power stations are significantly different from traditional synchronous power sources. Meanwhile
the energy storage stations have charging mode and discharging mode
which makes their fault characteristics different from those of renewable energy sources such as wind and photovoltaic. Therefore
the connection of electrochemical energy storage power stations will have a serious impact on the power directional elements of the distribution network. First
the fault characteristics of electrochemical energy storage power stations are studied. On this basis
the impact mechanism of fault characteristics of electrochemical energy storage power stations under charging/discharging operation mode on the directional elements of power grid protection is analyzed. Then
the fault identification method based on the principle of current selective tripping protection is proposed to effectively eliminate the misjudgment impact of the connection of electrochemical energy storage power stations on the power directional elements. Finally
the verification is conducted based on the PSCAD/EMTDC simulation platform. The results indicate that the phase difference variation between short-circuit current and voltage during the charging of energy storage stations leads to the incorrect operation of power directional elements on the side of the energy storage stations. However
the proposed protection scheme is not affected by the charging mode of the energy storage power stations and can quickly and correctly identify the fault location.
