Wind is an inexhaustible natural energy source that humans have used in one way or another for millennia. A great many wind farms with large numbers of wind turbines have been constructed in recent years around the world, and offshore wind farms are now becoming popular, particularly in Europe. Yokogawa provides a variety of measurement and control technologies that help to ensure the stable power supply by making operations more efficient and by enabling remote and centralized monitoring of multiple wind power generation systems.
Customer Challenge
Maintaining a stable supply of power to the grid even when varying wind conditions cause fluctuations in the amount of generated power
Solution
Yokogawa supplies an integrated power monitoring and control system and a battery control system that tracks how much power is being generated and manages the charging and discharging of the battery system to ensure a stable supply of power to the grid.
Enabling Technologies
STARDOM Network-based Control System
STARDOM’s autonomous controllers are highly durable and provide support for CANopen, Modbus, Profibus, and other network protocols.
FA-M3 Range-free Multi-controller
A high-performance programmable logic controller (PLC) that combines very high processing speeds with stable control features. It can be utilized to monitor and control the operation of individual wind turbines.
FAST/TOOLS SCADA
The FAST/TOOLS package optimizes performance for renewable energy applications. It ensures high availability and performance and supports online configuration.
WT1800 Power Analyzer
The WT1800 can measure the voltage, current, power, and frequency (for AC) before and after DC - AC conversion and before/after battery voltage conversion. Minimizing losses in these conversions improves the efficiency of the overall energy system.
DL850 ScopeCorder
The DL850 ScopeCorder is a modular waveform recording instrument that can simultaneously measure voltage, current, strain, acceleration, and other phenomena.
Customer Challenge
Minimizing the likelihood of having to shut down a wind turbine because of a controller failure
Solution
Yokogawa provides proven, highly reliable controllers that ensure maximum uptime for wind turbine facilities.
Enabling Technologies
FA-M3 Range-free Multi-controller
A high-performance programmable logic controller (PLC) that combines very high processing speeds with stable control features. It can be utilized to monitor and control the operation of individual wind turbines.
Customer Challenge
Monitoring operations at multiple wind farms that may be located all over a country
Solution
Yokogawa’s STARDOM network-based control system and FAST/TOOLS SCADA software support the integrated monitoring from a central location of operations at wind farms that may be located all over a country and which may utilize a variety of control and monitoring systems.
Enabling Technologies
FAST/TOOLS SCADA
The FAST/TOOLS package optimizes performance for renewable energy applications. It ensures high availability and performance and supports online configuration.
Customer Challenge
Using battery energy storage system (BESS) in order to ensure the stable supply of power to the grid even when there is a dip in power generation
Solution
Yokogawa’s network-based control system with its redundant SCADA helps customer’s stable and profit-maximized operation with following key functions:
• Operation planning and monitoring: Display required information of every BESS integrated in the system in remote control center by multi-screen, and let operators make the setting of schedule for constant power or load following for each BESS.
• Control and operations: Distributing the information to BESS for stable operations such as reference value for demand-power- level, reference-power (active/reactive) from the distribution management center and schedule warning alert.
• Battery monitoring: The charge-discharge rate, charge status and operation status of each battery are displayed.
Wind Power Generation Process
A wind power generation system, or wind turbine, is comprised of components such as an electrical generator, power converter, blades, hub, nacelle, and tower. It converts the kinetic energy of wind to mechanical energy in order to drive the electrical generator. A battery storage system is sometimes used at wind farms to ensure the stable output of power to the grid.
