The sun is an inexhaustible source of clean energy, and humans have used this in a variety of ways down through the ages. Today, solar power generation is a topic of considerable interest all over the world. With more than 100 years of control experience, Yokogawa now offers a fully integrated control and monitoring solution for solar PV and CSP power plants.
Challenges
Customer Challenge
Optimizing power generation efficiency by accurately tracking the sun as it moves across the sky
Solution
Yokogawa’s STARDOM controller accurately calculates the position of the sun and precisely controls the actuators that keep the solar pannels properly aligned with the sun.
Enabling Technologies
The Stardom RTU controller uses the Solar Position Algorithm of the National Renewable Energy Laboratory of the United States Department of Energy for single- and dual-axis tracking and positioning, and offers an inverter interface via Modbus TCP as well as DNP3 and Modbus RS interface options.
Collaborative Information Server (CI Server)
Yokogawa CI Server allows immediate improvement to production efficiency through digital transformation and reduction of operational maintenance whilst building a digital transformation framework.
Plant Resource Manager (PRM) makes predictive maintenance easy. Early detection of system and device malfunctions helps prevent catastrophic failures.
CENTUM VP Distributed Control System
The CENTUM VP DCS secures interruption-free “uptime only” plant performance for optimal productivity and profitability in the renewable energy field.
Customer Challenge
Presenting different kinds of data in such a way that they can be understood at a glance
Solution
Yokogawa’s CI Server employs a graphical user interface that represents data in a highly intuitive visual format.

Collaborative Information Server (CI Server)
Yokogawa CI Server allows immediate improvement to production efficiency through digital transformation and reduction of operational maintenance whilst building a digital transformation framework.
Customer Challenge
Large solar fields must be managed reliably and efficiently
Solution
Yokogawa’s CI Server can remotely configure the solar tracking controllers and obtain the detailed performance and status information needed to reliably and efficiently manage a large field of solar panels. The use of peer to peer communications reduces the communications load for the SCADA system.

Renewable Power Plant Controller
Synchronized high-speed power control, including PV smoothing/ramp control and energy shifting. Mitigates voltage and frequency fluctuations caused by solar intermittency.
Customer Challenge
Integrating the various systems and subsystems throughout a plant so as to optimize efficiency and ensure stable operation
Solution
Yokogawa seamlessly integrates the power generation system with subsystems such as the solar collection system and the heat exchange system. This facilitates the monitoring and control of the entire plant, thereby leading to increased efficiency and greater stability.
Enabling Technologies
Renewable Power Plant Controller
Bring clarity and reduce the cost of operations through direct, real-time asset monitoring and optimization that consolidates disparate system controls and visualizations into a single platform.
Customer Challenge
Using battery energy management system (BESS) in order to ensure the stable supply of power to the grid even when there is a dip in poer 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.
Enabling Technologies
Renewable Power Plant Controller
Guarantee the delivery of a fixed amount of energy by leveraging intermittent resources and virtually eliminating energy waste. Stabilize the power supply by coordinating and dispatching generation and storage assets in real time to compensate for sudden load changes.
Resources
- Yokogawa's HXS10 solar controller optimizes conversion efficiency at Australian solar cooling plant
- Accurate sun tracking and visualization of all process data
- Australian National University's "Big Dish" controlled by Yokogawa PLC and FAST/TOOLS SCADA
- FAST/TOOLS benefits us in many ways and allows us to clearly see the entire process, giving us the information we need to take immediate action
TSE proposed to customer a floating solar PV system that floats in water storage pond, cooling ponds, and wastewater ponds in the plant.
Yokogawa's CI Server and FA-M3 PLC contribute to the production of clean power for the plant.
- The NEP Solar team developed the control strategy and the Yokogawa engineers programmed the controller accordingly.
- The FAST/TOOLS software could be installed on the notebook PCs used by the development team, eliminating the need for costly dedicated servers.
Granite Power is a geothermal company that has developed GRANEX®, a patented direct supercritical fluid heat transfer technology for the efficient, eco- nomic, and zero carbon emission generation of electricity from low grade geothermal sources using the Organic Rankine Cycle (ORC).
- FAST/TOOLS SCADA system to remotely monitor the optimization of the process and make any required engineering changes to the live system.
- The Yokogawa control system (FAST/TOOLS, STARDOM, HXS10) monitors not only the sunlight but also the weather conditions.
Industrial hydrogen fuel cells can be used to produce hydrogen and oxygen from distilled water as well as run in reverse to generate electricity. Fuel cells can also be used in conjunction with intermittent energy sources like solar or wind to provide regulated continuous energy output.
Power monitoring package SMARTDAC+ GM and UPM100 system measures and quantifies the electrical energy consumption for each assembly line.
More than half a century has passed since Yokogawa developed Japan's first magnetic flow meter for industrial use in 1955, and today, Yokogawa's magnetic flow meters are widely used in a variety of applications thanks to features such as low pressure loss and maintenance-free operation due to no obstacles and moving parts in the fluid flowing pipeline.
In the paperboard market, which is expected to grow in China and other Asian countries, demand for paper color control has recently been increasing. To satisfy this demand, Yokogawa has developed a new color sensor for the B/ M9000VP system, a measurement and control system for both paper and coating machines.
