Control system for an SHPP (small hydro power plant):
- squirrel-cage motor as a power generator,
- IP54 metal cabinet with internal heating, providing the best protection against weather conditions, including lightning discharge,
- cabinet lighting and a built-in 230 V outlet for powering a computer,
- control circuits based on 24 VDC voltage,
- protection against incorrect power supply voltage, surge protection,
- grid parameter analyser,
- interaction with built-in motor protections,
- Siemens S7-1200 PLC and a 7″ touchscreen HMI operator panel for optimal control and operation of the cabinet,
- registration of local or remote acknowledgement requiring failures and malfunctions in retentive memory,
- implementation of event file in HMI for easy, in-depth analysis of the SHPP operation,
- Ursalink GPRS modem communicating with the PLC via Ethernet, providing access to all of the SHPP parameters,
- built-in UPs providing remote overview of the SHPP parameters in case of a power failure,
- sluice control modes: MANUAL, AUTO:
- control mode: MANUAL enables sluice control in emergency situations based on limit switches, bypassing the PLC and HMI,
- control mode: AUTO ? control is realized by the PLC. Modification of control parameters is possible only locally via the HMI panel,
- safe stop of the generator based on a safety switch,
- remote signalling of opening the cabinet,
- very cheap operation of a SIM card – approx. 5 zł/month,
- TraceMode SCADA enables monitoring of the SHPP, modification of its parameters, remote viewing of the plant’s state via Internet browser or smartphone and remote switching,
- 12-month warranty, which can be extended to 24 months,
- we provide electrical diagrams of the cabinet and enable system implementation by investors or third-party companies (FOR A FEE).
ATTENTION :
- details of the project’s scope depend on arrangements with the local Electrical Company.
