It looks like you aren't calculating your d/q correctly and it looks like it might not be routed to the correct location. You can test your d/q calculation against a sin wave, and you should get a dc response. your d/q response is still AC even when fed the ideal signals. You can use the existing d/q transformations in simscape or MCB if you provide the electrical angle.
