Wind Power

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.

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.
