NovoTAS-630 Turbine Automation and Protection System

Gedawin Novo Controls designs, manufactures and markets control and protection systems for the small hydroelectric generation industry. The NovoTAS-630 Turbine Automation and Protection System is the foundation of the Gedawin Novo Controls small hydroelectric generation control package. The NovoTAS-630 combines turbine start/stop logic sequence control, mechanical and generator electrical protection in one user configurable device.

Overview

The NovoTAS-630 is the latest model in a long line of controls designed specifically for the automation, PID turbine governing and electrical protection of small hydroelectric turbines and generators. The primary features include:

  • Automation of start-up, shut-down and emergency shut-down sequences
  • PID Governing of wicket gates/blades position using either pulsed or continuous control signals. Compatible with reaction and impulse turbines
  • Measurement of electrical conditions (voltage, current, power & energy)
  • Electrical unit protection & synchronization, sequence of events recorder (1 ms resolution) and log file data time stamping
  • Fault detection with alarm, soft shutdown or fast shutdown
  • Modbus TCP communication protocol
  • User programmable control logic sequences for site specific customization

Features

  • Size: 600 mm W X 287 mm H X 62.5 mm D
  • Power requirements:24Vdc @ 3amps
  • 48 x Discrete inputs: dry contact (68 with GEM expansion module)
  • 32 x Discrete outputs: relay driver to ground (48 with GEM expansion module)
  • 8 x VT & 8 x CT waveform inputs with 16-bit resolution
  • 16 x RTD inputs with 12 bit resolution: 3 wire PT100
  • 6 x Analog 4-20 mA inputs with 16bit resolution
  • 4 x Analog 4-20 mA outputs
  • 2 x Analog voltage output (+/- 10 VDC) for proportional hydraulic valve control (Gates/Blades for Kaplan or Gates 1/Gates 2 for Double Wheel Francis)
  • Tachometer input
  • 10/100Mbs Ethernet port for Modbus TCP communication
  • Modbus Master RS-485 port to connect to GEM expansion module
