(b)	Contingency outage is not present
(c)	Security is not present
(d)	All of above

12.

Secure post contingency is the state of the

(a)	Power system when contingency analysis is applied to the base operating condition with correction
(b)	Power system when contingency analysis is applied to the base operating condition with without correction
(c)	Power system when contingency analysis is not applied to the base operating condition
(d)	None of above

13.

The possible way to study thousand of possible outages is

(a)	Load flow
(b)	State estimation
(c)	Linear sensitivity factor
(d)	None of above

14.

Generation shift sensitivity factor is determined by [Where ‘i’ corresponds to bus in which the generator is connected, ‘l’ corresponds to the line under study, i.e. between the buses n and m, X _l is the reactance of the line, X _niand X _mi all the corresponding values in the sensitivity matrix]

(a)	$a_{l i} = \frac{1}{X_{l}} [X_{n i} - X_{m i}]$
(b)	$a_{l i} = \frac{1}{X_{l}} [X_{n i} + X_{m i}]$
(c)	$a_{l i} = \frac{1}{X_{l}} [X_{n i} + 2 X_{m i}]$
(d)	Not possible to determine

15.

Line outage distribution factor is determined by [Where ‘l’ corresponds to the line under study, i.e. between the buses ‘n’ and ‘m’ and ‘k’ corresponds to the outage of the line which is connected between buses ‘i’ and ‘j’]

(a)	$d_{l, k} = \frac{\frac{x_{k}}{x_{l}} [x_{i n} - x_{j n} + x_{i m} + x_{j m}]}{x_{k} - [x_{i i} + x_{j j} - 2 x_{i j}]}$
(b)	$d_{l, k} = \frac{\frac{x_{k}}{x_{l}} [x_{i n} - x_{j n} - x_{i m} + x_{j m}]}{x_{k} - [x_{i i} + x_{j j} + 2 x_{i j}]}$
(c)	$d_{l, k} = \frac{\frac{x_{k}}{x_{l}} [x_{i n} - x_{j n} - x_{i m} + x_{j m}]}{x_{k} - [x_{i i} + x_{j j} - 2 x_{i j}]}$
(d)	Any of above

16.
