a unique parameter for simulated_hydropowerrecorder is made for each node

[matrosoe]

Data tap showup as attribute_name.node_name making each attribute unique, so can't be compared across nodes

ex: 'simulated_hydropowerrecorder.Chipwi_turbine', 'simulated_hydropowerrecorder.Dapein_1_turbine', 'simulated_hydropowerrecorder.Dapein_2_turbine', 'simulated_hydropowerrecorder.Deedoke_turbine_1',

rather than each node having just one parameter called 'simulated_hydropowerrecorder'
