The testing system includes a real-time simulation working station, an RTDS (Real Time Digital Simulator), a DC control protection device and a VBE device. The real-time simulation working station is connected with the RTDS. The RTDS transmits current and voltage signals to the DC control protection device and VBE device through an analog quantity output board card and a power amplifier. The RTDS transmits commutation tap-position-changing signals and circuit and disconnecting link signals to the DC control protection device through a digital quantity output board card. The DC control protection device transmits valve triggering pulses and circuit breaker and disconnecting link switching instructions to the RTDS through a digital quantity input board card. A electrode current control protection device transmits valve triggering pulses to the VBE device and then the valve triggering pulses are sent to the RTDS through the digital quantity input board card after being processed by the VBE device. The testing system provided by the utility model can test all functions of the same-tower double-circuit engineering comprehensively.
