摘　　要：空间太阳阵列模拟器(Space Solar Array Simulator,SSAS)是模拟太阳能电池板在各种负载条件下的输出特性曲线,在航天器电源系统的地面测试领域有着广泛地应用。但是在实际测试环境中,太阳阵模拟器与被测航天器电源之间较长的测试线缆,严重影响了太阳阵模拟器输出I-V曲线的模拟精度,故一般采用补偿连接线的方式对模拟器的输出电压进行远端补偿。提出了一种简单的检测远端电压补偿端子连接线的连接状态的方法,并给出归一化的故障状态判断依据。该方法不仅仅适用于太阳能电池阵列模拟器设备中,也可应用于任何大功率电源需要对输出电压进行远端电压补偿的应用场合。The space solar array simulator(SSAS)simulates the output characteristic curve of the solar panel under various load condi-tions,which is used to complete the performance test of the tested power system,and is widely used in the field test field of the spacecraft power system.However,in the actual test environment,the long test cable between the solar array simulator and the power supply of the spacecraft being tested seriously affects the simulation accuracy of the output curve of the solar array simulator.Therefore,the compensation connection line is generally used to remotely compensate the output voltage of the simulator.This paper proposes a simple method to detect the connection state of the remote voltage compensation terminal connection line,and gives a normalized fault state judgment standard.This method is not only suitable for solar array simulator equipment,but also for any high-power power supply where remote voltage compensation is required for the output voltage.
