Definitions

  • the invention relates to a method for securing communicating electronic components, such as the DC / AC inverter of photovoltaic modules in photovoltaic systems.
  • Another way to prevent theft of photovoltaic modules after the EP 2 077 588 A2 consists of providing each of the photovoltaic modules with a GSM unit, which of course must then be provided with its own SIM card. This leads to considerable investment costs for the large number of SIM cards to be used and to ongoing connection costs, as well as additional energy consumption when establishing radio connections.
  • WO 2012/167909 A1 there is also a method for theft monitoring of solar modules and a photovoltaic system with a large number of solar modules for carrying out the method.
  • Theft monitoring is carried out here with an electronic monitoring unit which, for example, transmits the generated electrical voltage, the temperature of the solar modules, etc. to a central server, for example by means of GSM transmission, via a long-range communication network.
  • a first monitoring unit on a first solar module and a second monitoring unit on a second solar module are connected to one another via a communication network, the first monitoring unit functioning as a slave and the second monitoring unit performing the function of a master in a short-range communication network which takes over the Status information of the second solar module is transmitted to the central server via the long-range data communication network. If the data exchange between the first and the second monitoring unit is interrupted, the first monitoring unit takes over the function of the master, which then sends an alarm signal and / or status information to the central server via the long-range data communication network.
  • WO 2010/054840 A1 describes an anti-theft device for solar modules in which at least two solar modules are firmly connected to one another and from which each solar module can only be removed in a destructive manner.
  • the anti-theft device contains a steel wire which is connected to other anti-theft devices and which can only be removed from the respective solar module by damaging it.
  • fiber optic cables can be used instead of the steel wire, which are connected to a control room via the solar modules and connectors.
  • the entire photovoltaic system can be monitored by appropriately connecting optical fibers and by feeding in light and evaluating it when it emerges from the optical fibers.
  • Such an anti-theft device is very complex to install and difficult to repair in the event of damage.
  • a monitoring unit for (functional) monitoring of independently operated electrical systems such as photovoltaic systems, or wind turbines with a data processing and storage unit
  • the is connected to a communication network via a router and serves in particular as a power failure protection.
  • a constant power supply from an energy network is required for the operation of the routers and communication networks.
  • monitoring unit ÜE enables permanent control of independently operated electrical systems with regard to a possible failure of the power supply from an energy network and the fastest possible restart of the electrical systems, including by restarting the router (see Fig. 3 ).
  • a monitoring unit ÜE which can be connected to a communication network KN, for example the Internet, which is connected to a relay input stage RES and to a relay output stage RAS, which is the functional counterpart to the relay input stage RES, the relay
  • the input stage RES and the relay output stage RAS each work in the same variable voltage range from 3 V to 1,000 V.
  • the relay input stage RES is connected to the sensors, sensors and switches of an electrical system to be monitored via a monitoring input ÜWE.
  • there is an internal mains-independent power supply UVS the input side with the public 220 V network EN and the output side with the data processing and storage unit ZKE, as well as via a switch with the power supply SV of a router and other components. The router is restarted after a power failure.
  • the monitoring unit ÜE is equipped with an operating and display unit BAZ for control and manual control.
  • the monitoring unit ÜE can independently exchange information with the central server independently of the monitored photovoltaic system, there is a separate data processing and storage unit DS between the relay input stage RES and the relay output stage RAS of the monitoring unit ÜE, which is connected to a communication network such as the Internet IN, is connected.
  • the invention is based on the object of providing a method for securing communicating electronic components, such as the DC / AC inverter of photovoltaic modules in photovoltaic systems against theft, which does not require any intervention in the control of a photovoltaic system and which is always ready for operation guaranteed.
  • the method according to the invention functions completely independently of the manufacturer and does not require any intervention in a photovoltaic system or in the data traffic present in such a system, the existing communication also being used for monitoring, ie no new installation of data lines is necessary, which also simplifies the repair of a photovoltaic system becomes.
  • Monitoring is also carried out at night when the DC / AC inverters do not send any signals independently, i.e. when the photovoltaic system is inactive.
  • Fig. 1 is a simplified schematic representation of DC / AC inverters WR of a photovoltaic system without further details, such as the required photovoltaic modules.
  • the DC / AC inverters WR are each grouped together, with the energy supply for each of the DC / AC inverters WR in a group being provided via an associated sub-distribution UV, which are connected to an energy network EN via a main power supply HSV.
  • the DC / AC inverters WR are controlled via a common communication and data line KL (data bus), which are connected on the one hand to each DC / AC inverter WR and on the other hand to a central communication unit ZKE, which is connected to the Internet IN as a communication network or is connected to another communication network, whereby other communication options in the form of Ethernet communication or RS485 bus communication are also possible.
  • KL data bus
  • the monitoring unit ÜE for monitoring the data traffic between the DC / AC inverters WR and the communication unit ZKE has been expanded.
  • the monitoring unit ÜE is connected to one of the energy sub-distributions UV in order to supply power to the integrated mains-independent power supply UVS, the mains-independent power supply UVS can also be connected to the central communication unit ZKE via a power supply SV for its uninterruptible power supply.
  • the energy supply to the monitoring unit ÜE and other connected assemblies, such as the central communication unit ZKE is ensured, at least temporarily, and the function of the data processing and storage unit DS as well as the communication and data line KL and other data lines DL secured.
  • the monitoring unit ÜE is used according to the invention to check the communication paths, i.e. of data traffic, internally and externally, the central communication unit ZKE of the photovoltaic system with the help of the data processing and storage unit DS, for the secure notification of a central server and, if necessary, the restart of the corresponding devices, such as the central communication unit ZKE and the communication network of the DC / AC Inverters WR via the common communication and data line KL.
  • the monitoring unit ÜE is connected to the central communication unit ZKE via a data line DL. Indirect monitoring of individual solar cells can thus be carried out with the monitoring unit ÜE.
  • the monitoring unit ÜE is after Fig. 3 provided with a memory for storing the operating and device data SPG of a photovoltaic system, such as the type and number of connected devices, which when started for the first time via a data line DL ( Fig. 1 ) detected or programmed once between the monitoring unit ÜE and the central communication unit ZKL become.
  • a data line DL Fig. 1
  • Fig. 2 shows an alternative in which a main monitoring unit HÜE is additionally connected to a secondary monitoring unit NÜE via a data transfer line DFL, the secondary monitoring unit NÜE being coupled to the end of the communication and data line KL via a query line AL, which is not connected to the central communication unit ZKL.
  • the NÜE is connected to a sub-distribution UV for power supply.
  • the structure of the main monitoring unit HÜE and the secondary monitoring unit NÜE basically corresponds to the structure of the ÜE Fig. 3 .
  • these data are queried continuously or at time intervals by the monitoring unit ÜE and compared with the data stored in the memory for operating and device data SPG, with corresponding information about the central communication unit ZKE and the like being found in the event of deviations Internet IN to the central server eg as an e-mail message or as an alarm.
  • the monitoring unit ÜE monitors the mains supply of the devices to be monitored by the sub-distributors UV, in particular the central communication unit ZKE and, if a mains failure is detected by the relay input stage RES, at least temporarily takes over the mains supply via the relay output stage RAS, which also has a switching output SAG the central communication unit ZKE is connected to the emergency power supply.
  • the data processing and storage unit DS is additionally coupled to an internal communication unit IKE, which, if necessary, connects to a Communication network KN and above to the central server, or an emergency server.
  • the check is carried out continuously, or preferably at adjustable time intervals.
  • Variant 3 consists of a combination of variants 1 and 2
  • a central server is to be understood as a far-away server for remote control of the photovoltaic system via the Internet or another communication network, or another central monitoring unit.
