Power Systems Training Institute (PSTI), Bangalore
The Central Electricity Authority (CEA), an attached office of Ministry of Power, Government of India established the Power Systems Training Institute at Bangalore in 1972 for providing specialised training in the field of Power Systems mainly to the engineers from Power Utilities. The Institute is headed by a Chief Engineer.The Institute is located in its own campus and hostel facilities with boarding arrangements are available to the trainee officers. Specialised laboratories,a well equipped library and a lecture hall complete with modern teaching aids have been set up at the Institute campus for meeting the training requirements. For the engineers attending training programmes in the various disciplines, facilities are provided in the Power Loading Simulator laboratory, Communication laboratory, Relay laboratory and Computer laboratory. | The Institute has a state-of-the-art digital computer based Despatcher Training Simulator. Power system behaviour under different operating conditions can be studied in the simulator. The faculty for the training programmes comprises in-house faculty as well as experts drawn from I.I.Sc., CPRI, CDAC, DoT, ITI, Utilities and manufacturers. Training programmes are offered in ten different disciplines in the field of Power Systems and the duration of the course varies from one to four weeks depending upon the programme. In 1983, the Institute had also organised and conducted a special training programme for the benefit of power system managers from ten countries in the ESCAP Region. In addition to these, the Institute is also conducting special courses on HRD programme. |

i) Despatcher Training Simulator Laboratory
The DTS laboratory is commissioned in February '90 with the assistance of UNDP. This is a digital simulator in power simulating power system network. Presently a representative system of Northern Regional Network is simulated. It has all types of generation like hydro, thermal, nuclear, gas and pumped storage etc and transmission schemes covering 220, 400kV and the generation voltages. Also most of the transmission equipment like transformers, transmission lines, capacitor banks bus/line reactors, SVSc, CBs, Isolators etc. Are represented. The realtime simulation is carried and for normal and emergency conditions of the network with initial conditions. The behaviour of various elements for different loading conditions can be studied in the simulator. Time tagged or manual events can be introduced into the simulator when the simulator is going on. Protection schemes cold be implemented with the help of voltage relays, frequency relays, rate of change of fr. Relays, over current relays etc. The actual system occurances can be simulated and saved as save cases. Hence it is a comprehensive training tool for training of power system and load despatch operators. This lab is only one of its kind in the country.
Primarily designed: · To train engineers in the techniques of economically controlling the system frequency of large power networks · To study alternative operating procedures · To investigate the range of characteristics and responses associated with power generation Parts of the Simulator: a) Main Simulator unit - simulates an area of Load and Generation with system variables displayed in analogue form. · six generators (steam, hydro, gas, base generation) including a pumped storage scheme · load: by pre-recorded programme; available on tape · additional grid network (for practising export and import) b) Load disconnection unit c) Tape recorder - providing load curve to the system d) Chart Recorder - taking hard copy output of system variables The simulator is 4 times faster than real-time. Three hour load curve is simulated in 45 minutes. Operation: Trainee engineers are given a load curve and characteristics of the system units. They prepare a load schedule in a response sheet such a way that: * The frequency is maintained at 50 Hz * The system units are operated economically * Import/export commitments are met System generation and load at the start of the simulation time is set. The simulator is transferred to programme mode. Tape drive feeds the load curve to the system. Trainees carry out the instructions as per the response sheet. Frequency is plotted. At the end of the simulation, total cost for the duration of the simulation is noted and compared with the standard cost.

The Relay Simulator Laboratory is housing a set of four panels with indications for the type of fault and the status of circuit breaker and isolator.Each of the indicators on the panel and the isolator, breakers conditioning can be actuated through the control panel switches. Hence the directional relays can be simulated through actuating a set of indications, Isolators, and Circuit Breakers. Based on the indications the trainee will identify the type and location of fault on the one line diagram.
