GRID INTEGRATION AND WIND FARM MANAGEMENT
GRID INTEGRATION AND WIND FARM MANAGEMENT
ENERCON's wind energy converters are engineered to enhance grid stability by integrating a high proportion of renewable energies. They are designed to be flexible, grid-friendly, and reliable, contributing significantly to global grid stability.
The design features a rotor directly connected to an annular generator, with power fed into the grid through a full-scale converter system. This includes a rectifier, DC link, and inverters, allowing for high rotor speed variation and robust operation. The system ensures maximum power feed while adhering to grid requirements, even under fluctuating conditions.
ENERCON converters enhance frequency stability through power-frequency control, adjusting power feed during overfrequency and underfrequency conditions. The 'Inertia Emulation' function mimics conventional power plant behavior, using stored rotational energy to stabilize frequency during drops.
Voltage stability is achieved through reactive power provision. ENERCON converters offer a wide reactive power range, which can be expanded with the 'Q+ option' and 'STATCOM option' for enhanced grid support, even without wind.
The 'Fault Ride Through' (FRT) function enables converters to manage grid faults like undervoltage and overvoltage, maintaining active power supply and providing voltage-supporting reactive current. This function is adaptable to specific grid requirements and certified to stringent standards.
The ENERCON SCADA system allows for remote monitoring and control of wind energy converters. It is modular and adaptable, ensuring maximum yield and compliance with grid connection criteria. It includes generation management for optimal power control and bottleneck management to minimize yield losses during grid constraints.
ENERCON's technologies and systems are designed for seamless integration with grid structures, providing reliable and stable operations while supporting the transition to renewable energy sources.
The ENERCON SCADA system manages and monitors wind farm operations, providing real-time and historical data on performance metrics like operating hours, power output, and wind speed. This data can be visualized and downloaded for offline analysis.
The system includes SCADA Remote, SCADA Wind Farm Controllers, SCADA Interfaces, SCADA Meteo, and SCADA Power Consumption Management. The FCU E2 controller offers control properties tailored for specific grid connections.
The ENERCON Service Info Portal provides access to service information and data related to wind energy converters, offering functionalities like service orders, maintenance reports, and yield analyses, with secure data protection.
ENERCON provides a full-service package for connecting wind farms to high voltage grids, ensuring quality through a prequalification process and regular supplier audits.
ENERCON offers technical support for wind farm projects, assisting in simulations, compliance tests, and integration with other renewable systems like photovoltaic and biomass plants.

GRID SUPPORT FROM ENERCON WECs VOLTAGE STABILITY Reactive power is required for voltage stability and to compensate operating equipment in transmission and distribution networks. The full-scale converter concept means ENERCON wind energy converters can provide reactive power very flexibly and dynamically. P Large reactive power range Inertia Emulation – Synthetic flywheel mass for the grid FREQUENCY STABILITY Power-frequency control In a power supply network, there needs to be an equilibrium between generation and consumption at all times. If this is not the case, the frequency will deviate from...

ENERCON SCADA SYSTEM ENERCON SCADA SYSTEM GENERATION MANAGEMENT SYSTEM POWER CONTROL FOR MAXIMUM YIELD If the cumulative nominal power of the WECs in an ENERCON wind farm is greater than the grid connection capacity at the network connection point, a special power control system ensures that the available grid connection capacity is used to the fullest. The ENERCON SCADA system (Supervisory Control and Data Acquisition) is the platform for remote monitoring and control of wind energy converters. It has been established for many years and is an integral component of ENERCON’s service and maintenance...

ENERCON SCADA SYSTEM ENERCON SCADA SYSTEM ENERCON SCADA WIND FARM CONTROLLERS On a wind farm consisting of multiple ENERCON WECs, the wind farm‘s behaviour at the grid connection point can be controlled using an ENERCON SCADA wind farm controller, such as the ENERCON SCADA RTU or the ENERCON SCADA FCU E2. The local requirements determine which wind farm controller is suitable. This decision is made on a project-specific basis. FCU E2 can be optionally equipped with digital and/or analogue I/O modules. The ENERCON SCADA FCU E2 not only provides fundamental control properties such as P, P(f), Q,...
