DEIF’s Hydro Turbine Control Solutions

Conventional hydro turbine control systems are generally complex and fragmented setups that include a general purpose PLC, separate generator protection relays, synchronisers, governors, water level controls and other auxiliary control systems. These old generation hydro turbine control and protection systems may no longer be up to the task of meeting today’s requirements for cost-effective and reliable operation of the hydro power plant. These systems may also be vulnerable to failures due to their complex nature. The suppliers or manufacturers of these systems being diverse and small & medium enterprise, which implies that you as a customer may not get the support when required, which could result in decreasing availability and deteriorating operational reliability of a power plant that can land in loss of revenue.

DEIF, a company of Danish origin with global presence, is one of the world leaders in control solution for the power generation systems on land and marine segments. DEIF with its eight-decade of experience has developed control solutions for hydro power, the largest and most economical source of renewable energy on Earth. In order to guarantee optimised power plant operations, increase safety and simplify maintenance; DEIF has developed integrated solutions that are capable of performing large number of functions compared to standard systems. Due to its integrated products and solutions, DEIF can reduce the maintenance costs to a minimum.

DEIF India Pvt Ltd, a subsidiary of DEIF A/S, Denmark, is the Centre of Excellence for hydro power applications. DEIF India develops and provides innovative solutions for power management and control of micro, mini and small hydro power generating sets for the whole world. Their systems have been installed and running successfully in large number of hydro power plants countrywide over a very short time span. DEIF’s product Delomatic 400 Hydro is used by numerous renowned OEMs and end-users including Himachal Pradesh State Electricity Board Ltd and Uttarakhand Jal Vidyut Nigam Ltd, the states with maximum hydro power potential in India.

Globally local existence
DEIF’s “glocal” approach combines leveraging global experience with strong local presence and expertise. The company’s local experts work hand-in-hand to meet exact customer needs at every stage of the project. DEIF HYDRO is supported by global sales and service setup which gives a global reach and the ability to serve its customers in any corner of the world. After completion of the project, DEIF offers an extensive local support network in order to ensure high availability of maintenance and other services. By doing so, the company offers a highest degree of operational safety and efficiency.

Technology through innovative solutions
DEIF invests heavily in research and development globally, to provide state-of-the-art technology that meets customers’ needs and stay at the forefront of technological innovation. The expertise and vision of its designers and their partnership with different fields of power control equipment such as marine, steam, gas and diesel allow DEIF to consistently offer cutting-edge technology to its customers in hydroelectricity generation sector as well.

Tailor-made solutions for specific requirements
Every project is different in terms of challenges and requirements. Local conditions or budget limitations are also determining factors for hydropower projects. DEIF offers integrated and cost-efficient solutions of different scope according to customer-specific requirements and capabilities. In the development process DEIF’s goal is to maximise efficiency by customising its solutions to reach the best possible solution for each client, thus gearing up the customer’s profit to a higher level.

Hydro Turbine Generator Control
A customised solution, DEIF’s integrated hydro turbine generator control solutions economises installation costs significantly by using fewer components and lesser wiring compared to systems that require multiple units to provide synchronisation, protection and PLC functionality.

Delomatic 400 (DM400) Hydro-controlled plants offer fully automated control for stable optimised operation and require less maintenance and fewer man hours. The Delomatic 400 Hydro is compatible with all types of turbines and flexible and easy to adapt with simple parameter settings. Critical functions such as speed governing, generator protections and synchronising are fully integrated with password-protected features for maximum security.

The controller’s Human Machine Interface (HMI) is easy to operate. Based on the graphic screens embedded in the DM 400 Hydro unit itself, the screens are uploaded to a PC like any other interactive webpage graphics using USB or TCP/IP communication, enabling simple password-protected remote control and monitoring.

The advantages to DEIF’s Delomatic solution go beyond savings, wiring, construction, engineering and maintenance. It is also a flexible solution equally suited for new installations and retrofits, designed to control hydro turbinegenerators ranging from 2 kW to 20MW along with its auxiliary equipment.
