Is there any sense to use polarised betting range at river at micros? E.g. when we have tptp or something stronger at river,and board is not wet.E.g. we jam for value 3 time,one time for bluff.Is there more +ev with that play or should use standard lines?

Ofc there is sense in using polarised range. Unfortunately the question is unclear, try an example.

In general ranges are more polarised and bets are higher on wet boards.

Betting a polarized range on the river is kind of the aim of the game.
You want to be balanced between value hands and bluffs in the right proportions (it's 2:1 value:bluff if you make a pot-sized shove, but more value-heavy if you go smaller), such that your opponent is "indifferent" to calling with his bluff-catchers, because they will only break even. If you make villain's range have an EV of zero, it means your betting range has an EV of "pot". It's obviously pretty good for you if you have an EV of pot and villain has an EV of zero.

This doesn't mean that TPTK should always be in your river shoving range. In many spots, it's not strong enough to go into a polarized betting range, as you'll use other hands like sets, straights and flushes instead.

You'll no doubt be familiar with the feeling of dread you get when you have TPGK on the river and villain shoves. You're not sure if you should sigh-fold or make a crying call. That is the cage that you should be trying to put your opponent into. If you bomb the river with a polarized range, you make villain cry. Your winrate is made of villain's tears.
