Block Diagram
Peak Cut Mode
If the maximum demand power exceeds the contract power and uses a certain amount of time, the power user will be charged a penalty according to the number of times exceeded.
A function that allows the emergency generator to share the amount of power that exceeds the contract power with Peak Cut Mode
Demand Response (DR) Mode
A system in which electricity users are compensated financially by reducing the use of grid electricity when the electricity market price is high or when the electricity system reserve ratio is low
Customers participating in the demand response business can participate in the electricity demand response trading market through reduction of emergency response obligations and voluntary demand reduction
Emergency generator automatic inspection mode
Mode to automatically inspection the emergency generator by the program set in the grid tied CTTS
1. Automatic emergency generator start
2. Generator no-load operation inspection
3. Emergency generator inspection according to load
- 25% - 50% - 75% - 100% - 110% Step Test
- Load operation at 100% load for more than 60 minutes, etc
MV transformer uninterruptible transition system using LV CTTS -
Transformer Parallel Operation (Option)
Non-interruptible automatic transformer transition function through Touch LCD instead of conventional manual sequential transition
Stable parallel operation function through synchronized operation by monitoring voltage difference, phase, and frequency
Uninterrupted power supply is possible because uninterrupted transition is possible through parallel operation.
Maximizes the convenience of safety managers by enabling remote automatic transition
ESS uninterruptible transition system (Option)
Hybrid uninterruptible system consisting of STS built-in G-CTTS and short-cycle ESS
Diesel generator frequency and voltage variable control (VVVF) possible
CTTS capable of parallel operation and power control with the system or PCS
Built-in high-speed electronic circuit breaker capable of shutting off the system within 4 ms in case of power failure
