ERACS is ERA Technology's suite of power systems analysis software. It allows network design and planning engineers to simulate electrical power system networks quickly and easily to judge their correct, safe and timely operation under user defined, and sometimes arduous, situations. ERACS power engineering software is at the forefront of development taking account of both the continuing pressure for ever easier operational software and the increasing technical needs of modern engineering. The name ERACS has been synonymous with quality, reliability, accuracy, ease of use and adaptability to changing market needs.

The economic design of power systems is critically dependent on being able to predict the system behaviour under both normal and abnormal operating conditions. Hand calculations and estimates are possible but increasingly expensive in engineers' time and run the risk of introducing errors resulting in significant safety and reliability implications. ERACS saves costs, reduces risk, improves quality, and increases reliability and safety.

ERACS Screen Shots
ERACS results may be displayed on the single line diagram or in graphical form as shown in this harmonic impedance plot. Motor starting is only one of the many different uses of the Transinet Stability program which also includes: voltage dip profiling, generator load application and rejection tests , loss of generation, system synchronising, system stability studies, AVR and governor testing, wind farm analysis (torque variation studies), mixed frequency system analysis ERACS's user friendly graphical user interface allows single line diagrams to be constructed with ease and results displayed at user defined locations The Protection Co-ordination program may be used for the selection of protection devices, protection grading studies, protection stability studies, protection planning philosophy and performance checking, protection system safety documentation

System
ERACS is PC-based, fully integrated and has an easy-to-use interface. The data is entered once only in a central database, making data management a very simple procedure. Networks for simulation by ERACS may be either radial or fully interconnected systems or a mixture of both.

ERACS can be used in power systems engineering for modelling, loadflow analysis, fault analysis, harmonic analysis, system stability and protection co-ordination on all types of power system, including wind turbine modelling, AVR modelling and governor modelling.

ERACS software options
The following program modules and options are available:
Graphical user interface
Loadflow
Fault (classical)
Fault IEC909
Harmonic injection
Harmonic impedance
Transient stability
Protection co-ordination
Universal dynamic modeller (AVR modelling, governor modelling)
G5/4
Stand alone or network versions
10, 50, 100, 150, 300, 500 and 1500 busbar versions

Quality
ERACS is developed under ERA's ISO 9001 and TickIT certified quality system.

Why ERA?
The ERACS suite of power systems analysis software is in constant use by experienced ERA power engineers for system design and planning purposes. Therefore, they have direct input into the program development to incorporate best practices currently in use within the electrical industry . ERACS' wide user base (including offshore, marine, mining, utilities, transport and academia) is also encouraged to contribute to the development and direction of the programs. In this way the ERACS programs are constantly moving forward, providing real benefits in terms of reduced study times and improved technical capability to users, and in meeting the specific needs of engineers with practical problems to solve.

The provision of a dedicated ERACS user website and support 'hotline' further benefits its user base. Staffed by electrical/software engineers with a great depth of understanding of the latest programming techniques and tools, they also have direct access to ERA's own leading power systems engineers for technical support in times of need. ERA prides itself on its fast response time to technical queries from its software users.

ERACS includes sophisticated wind turbine generator models and load torque profiling options, Hydroelectric, wind and wave power generation schemes may be modelled within ERACS
