Moeller Operating Engineering:
Expertise in Renewable Energies and Grid Integration!

System certification
The system certificate is a prerequisite for obtaining the grid connection. This confirms to the system operator and the grid operator that grid-compliant operation of the system is possible. At the end of the certification process, M.O.E. prepares the Power Park Module (PPM) Declaration of Conformity, which certifies the correct implementation of the planning documents. In accordance with the national and international grid code requirements of the NC RfG or VDE, M.O.E. offers the entire documentation including the commissioning declaration and the extended commissioning declaration for prototypes.

Unit certification
The unit certificate, which forms the basis for system certification, includes the testing of power generating units such as wind turbines, solar inverters, CHPs, hydropower and storage facilities. It takes place on behalf of all power generating units of the series. In accordance with the European Network Code (NC RfG), the corresponding operating resource certificates can be issued for all European countries in compliance with the national specifications.

Component certification
For all essential components (e.g. parc controllers, protective relays, compensation systems) which are located in a power generating unit or plant, a component certificate or an equipment certificate can be issued in accordance with NC RfG. With the component certificate, the manufacturer or operator receives proof in accordance with national grid codes that the properties and functionality of a component comply with the guidelines. This proof of quality provides the manufacturer or operator with the necessary proof and significantly facilitates unit and system certification.

Individual certification assessment procedure for power-generation facility
The verification methods mentioned are not suitable for every power generating system. With the so-called individual certification assessment procedure for power-generating facility (system certificate C), a system certificate can be issued without submission of a unit certificate. The proofs in the procedure also guarantee a safe and permanent grid connection of the power generating system. M.O.E. offers all associated services including certification, model validation, measurement and monitoring from a single source.

Information Security Management Systems
Critical infrastructures depend on secure IT systems and a functioning Information Security Management System (ISMS). This concerns among others, the operation of electricity and gas grids, decentralised power generating system and plants or systems for controlling electrical output. In order to protect and independently test these systems, M.O.E. has competence in the area of ISO / IEC 27001 and ISO / IEC 27019. This also applies to the corresponding IT security catalogues of the Federal Network Agency.

Acoustic measurements and forecasts
In order to protect the environment, the Federal Immission Control Act stipulates limit values for noise emissions and immissions, which must be met by wind turbines, CHP plants and industrial facilities, for example. M.O.E. is accredited as a testing laboratory for the determination of noise at technical installations and is also notified as a measuring point in accordance with § 29b BImSchG (Federal Immission Control Act).

Measurement of electrical properties
On-site measurements can be used to check the electrical properties of power generating units and systems, such as harmonic measurements. These measurements can provide the necessary data and evidence for certification and the individual verification procedure.

Electrical components
The plant operator shall ensure that electrical systems and equipment are checked for their proper condition at regular intervals. The inspection body of M.O.E. GmbH is accredited according to DIN EN ISO / IEC 17020:2012 and thus guarantees its customers the highest level of expertise and maximum quality in the field of inspection. Accreditation as an inspection body covers the inspection of power generating systems with regard to the conformity assessment for the system certificate and the metrological proof of protective equipment at all voltage levels. In addition, testing according to electrical safety e.g. DGUV V3 and monitoring of the system-relevant parameters during the operating phase e.g. according to chapter 11.5.5 of VDE-AR-N 4110 / 4120 are offered from a single source.

Mechanical components
All wind turbines are to be inspected at regular intervals on the support structure, the machines and the rotor blades by an independent expert. If these deadlines are missed, there is a risk of losing the building permit, type approval or the insurance cover. The M.O.E. experts are recognised by the Bundesverband WindEnergie e.V. (German Wind Energy Association) and inspect at any stage of your project.
