Modular monitoring solutions ensure regenerative production of electricity
Monitoring technology from TELE reduces the risk of failure with wind power or photovoltaic systems and increases their cost-efficiency. For reliable operation, WatchDogs monitor the recharging status of the rechargeable batteries of the pitch control system, the obstacle illumination and the supply grid with wind power systems. With photovoltaic systems, the monitoring solutions avoid an inefficient mode of operation with insufficient sunlight and control the in-feed from small power plants into the network grid.
WatchDog safeguards wind power plants
Wind power plants are unmanned and decentralised power plants that are operated autonomously and require special monitoring technologies. The TELE WatchDog G4UF500V03 controls the recharging status of the rechargeable batteries of the pitch control system for over- and undervoltage. This prevents an overloading of the energy memory which could otherwise shorten the lifetime. For operational reliability, it is decisive that enough energy is available at any time to be able to turn the rotor blades out of the wind if there is excessive wind pressure or when the generator fails. Disruptions in the obstacle illumination must also be immediately recognised and reported, as should problems in the supply grid of the wind power plant. For this purpose, TELE?s WatchDog G2IM10AL10 controls the power consumption of the obstacle illumination. Thanks to the integrated time functions, non-constant flows, such as with flashing light, can also be easily monitored. The robust and reliably built WatchDog has a flexible supply voltage and a three-way disconnection (supply/measurement/output) with a measurement surge voltage of 4 kilo volts. In addition, the voltage monitor G2PM400VSY20 24-240V monitors the mains supply grid. Due to the setting options of the switching thresholds, the monitoring of the asymmetrics and the optional monitoring of the phase sequence, the WatchDog can be adjusted to any requirement. If problems occur in the supply grid, these are reliably detected.
Application
Increasing the cost-effectiveness of photovoltaic systems
Serially switched photovoltaic systems supply high direct current voltage with optimal sun status and a cloudless sky. With low sunlight, however, the voltage and thus the efficiency of the inverter are reduced. With minimum sunlight, the inverter and its control unit even consumes more energy than that supplied by the photovoltaic system. To avoid such losses, the WatchDog G4UF900V01 switches the photovoltaic system off with a defined minimum voltage. Only when the inverter can be ideally operated again does the system go back onto the grid. The voltage monitor G4UF900V01 works in a measurement range up to 900 volts and itself consumes minimal energy.
Application
Grid monitoring prevents impermissible electricity in-feed
Grid operators normally do not have any opportunities to control the electricity generation of private grid suppliers. To guarantee grid reliability and exclude uncontrolled energy in-feeds in the form of isolated operation, it must be possible to automatically disconnect private power plants ? independently of the energy production ? from the grid as needed. According to the DIN standard VDE 0126-1-1, which is also relevant for Austria, an autonomous switching point must monitor the electricity in-feed from, for example photovoltaic, bio gas or CHP plants into the 230-/400 volt grid and, if the grid fails, be able to interrupt within 200 milliseconds. The WatchDog G2FW50HZYFA02 from TELE fulfils this requirement by reliably measuring the grid voltage and frequency and, if needed, disconnecting its own energy generation system from the public low-voltage grid. The WatchDog G2PW400VF02 also reliably recognises a possible isolated operation. The TELE WatchDogs thus ensure the required monitoring functions with separable and lead-sealable devices independently of the inverter.
