So I'm doing some modelling in a power systems simulation software (PSCAD)

I'm using the integrator block in that software.

Now unlike SIMULINK PSCAD doesn't offer a \$ 1 \over s \$ block but offers a \$1 \over s*T\$ block where \$ T \$ is the time constant.

I just want a simple integration operation done, i.e:

When I input

$$ A*sin(100t) $$

I want to get

$$ -(A/100)*cos(100t) $$ What should I set the time constant \$ T \$ to get this basic result?

\$\frac{1}{sT}\$ is just the same as \$\frac{1}{s}\frac{1}{T}\$

So set T = 1 or use it to set the gain of your integrator
