Title:
REMOTE REAL-TIME SIMULATION SYSTEM FOR SAFETY AND STABILITY CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/011066
Kind Code:
A1
Abstract:
The present invention relates to a remote real-time simulation system for a safety and stability control device, comprising: a real-time simulation device, a signal conversion device, and a safety and stability control device; the real-time simulation device is connected to the signal conversion device, and the signal conversion device is connected to the safety and stability control device; the real-time simulation device receives a direct current blocking failure command, performs real-time simulation, and sends an obtained analog signal to the signal conversion device; the signal conversion device converts the analog signal into a first signal and sends the same to the safety and stability control device; the safety and stability control device receives the first signal, and according to a preset strategy table, emits a generator-tripping and load-shedding command to the signal conversion device; the signal conversion device converts the generator-tripping and load-shedding command into a second signal and sends the same to the real-time simulation device; the real-time simulation device executes a generator-tripping and load-shedding action according to the second signal, and sends a current system state to the safety and stability control device; when the current system state is a stable system state, the safety and stability control device executes the generator-tripping and load-shedding command.
