This change set requires the "30.0" or later platform version. One or more of the listed organizations is on a version incompatible with this change set. You can only select an organization for upload that is running the required version or later.
I have checked the versions on the triggers and classes and they are all pre 30.0. I have some new custom fields and some workflow rules and field updates. How do I tell what is causing this problem and how do I fix it?

You cannot control the version of Salesforce your org is running. Until your Production org is upgraded, you will only be able to deploy Change Sets that use API 29 or earlier.
You can create smaller change sets, and try deploying them. This will get the changes to Production that are possible.
