Island Map Generator

[Danel Potvin]

Thegenerator intentionally makes unrealistic terrain that was designed for the needs of our game, Realm of the Mad God[1]. Back in 2010 I wrote an article about the algorithms[2]; the original demo was in Flash[3]. Later I wrote a stylized map output that I then reused here.

Also take a look at mapgen4, my newer map generator that allows painting your own mountains, valleys, and oceans. It then simulates evaporation, wind, and rainfall, generating biomes and rivers that fit your map.

I hired a 2,4 KW petrol generator and the invertor would charge the batteries. However when I got GEM services (experienced generator / invertor technicians) to check the generator they found no issues. They put in the new batteries but could find nothing wrong with it. When they proceeded to try and make the SMA invertor work they were as mystified as the previous engineer

When the generator is on, the invertor tries to synchronise with the generator and as soon as it tries to start charging, the generator voltage plummets to below 180V then fault code W351 and W319. With all the following tests the same thing happens & the voltage drops so fast that the pitch of the generator engine does not change (about 2 seconds)

I am currently working on a setup with very instable 160-250 volt 55-65 hz grid - 60 Ampere single phase grid, three parallelised 48/5000 Quattros on a 23 kW LiFePo4 battery and a 21 kW @ 60 pieces x 350 Watt solar panel grid which I consider to connect DC wise with 4x Smart Solar Can Bus 250 MPPT tracker to the battery directly.

1. grid is nominal 60 Hz while most machines such as pumps and AC connected to the system will be 50 Hz. Understood Quattro cannot change frequency. Consider to implement an AVR voltage regulator and combined frequency shifting device. To adopt 60 Hz down to 50 Hz. However expensive. Any ideas, or alternatives ?

2. we have a Generator 47 KVA 3 phase 400 Volt 67 Ampere Max - 50 Hz - with ATS but only a single phase system. I am hesitant to rebuild the system for 3 phases as to better balance the load among 3 parallelised Quattros. Anyhow installation so far is single phase and grid is also single phase.

I cant comment on speciffoc victron kit, if it even exists, but I have grid connected many generators on Hydro systems that are either an odd frequency or have to change their frequency to match water conditions...

It seems to me that simple is better. Rectify whatever you have so frequency is off the table and then charge from the DC.

There is probably a product for that and if the voltage is way off whatever the chosen charger will handle a basic transformer will bring that into the ballpark before you rectify it.

I know Victron produce kit that would 'probably' do the job but I am not an expert and dont want to give you an example, or even a possibility, as I could well be suggesting kit be used inapropriatly or just talking nonesense.

Somone more aware of Victron specs may be in a position to suggest a product that will take DC, with a bit of ripple, and make stable AC to feed your chargers... All you would have to do then is set under frequency rolloff on the grnerator and manage charge current based on the rectified voltage.

Victron have products that do that, DC to AC whilst managing power. but as I said I can't comment on weather thay will handle rectified AC as opposed to DC on their input so cant actually suggest anything speciffic.

So here I am, complaining about the inconveniences of the generator for the humans on the island, but what about its more important inhabitants. I doubt that the White-tailed Tropic birds, the White Fairy Terns, the Seychelles Magpie Robins, the Seychelles Warblers and the Giant Land Tortoises are too happy about the deafening chugging of the generator.

Concrete was poured this week for the equipment pads for the new generator, load bank, and fuel tank. After the concrete cures, the forms will be stripped off next week. Electrical work continues on the various conduit runs into the pump station building. Delivery of the new generator is anticipated in June.

The rockery relocation is now complete; concrete formwork was completed yesterday for the new fuel tank, load bank, and generator concrete pads. The next steps include subgrade, forms, and rebar inspections followed by Dalton Electric installing conduit stubs before pouring concrete.

This project is currently on hold pending PSE crews lowering their power conduit that is currently in conflict with the designed rock wall. Once this is performed, McClure and Sons will return to complete the rockery, pour the concrete pads, and install new electrical conduits from the generator pad to the reservoir building.

Notice to Proceed for the contractor, McClure and Sons is scheduled for July 19, 2023. Initial work on-site incudes some tree removal, clearing/grading, and rockery work to make room for the generator and related equipment. Trees will be replaced on-site following the completion of the construction.

The construction contract was awarded to McClure and Sons Inc. at the November 15, 2022, City Council meeting. There are long lead times on items such as the diesel generator, transfer switches, and electrical components. Construction is expected to begin in August 2023.

The City has decided to add another component to this reservoir generator design which will allow for a direct hookup during annual load bank tests. Work on this is anticipated to start later in November.

The Island Home canceled its 8:15 am departure from Woods Hole and its 9:30 am departure from Vineyard Haven. The vessel would sail its route again starting with the 10:45 am trip. Outside of the generator problem, the Island Home also had issues with its doors opening, forcing the 2:30 pm departure from Vineyard Haven to be canceled.

Perhaps we should rename is the Broken Home? What is going on at the Steamship Authority this year? The lifeline to the Islands? Do they even know their own slogan? Some serious oversight and an overhaul of leadership are beyond due.

Urban Weather Generator [UWG] estimates the hourly urban canopy air temperature and humidity using weather data from a rural weather station. It takes a rural epw file and the *.xml (or *.xlsm) input file, which describes your urban canyon.

The model is based on energy conservation principles and is a bottom-up building stock model. The model takes input parameters that describe urban morphology, geometry, and surface materials. The urban morphology parameters are similar to those used for existing building energy performance simulations. The model variables are described in detail in Model Parameters Description page.

UWG has four coupled modules: the rural station model, the vertical diffusion model,the urban boundary layer model, and the urban canopy + building energy model, and is described in detail in The urban weather generator.

The boundary conditions of the urban canopy and urban boundary layers are shown below. The model estimates building energy consumption at the city scale, specifically accounting for the interactions between buildings and the urban environment.

The model been tested for Basel, Switzerland; Toulouse, France; and several neighborhoods in Singapore [detailed in "Computationally efficient prediction of canopy level urban air temperature at the neighborhood scale", to be published in Urban Climate and summarized here ].

The simulated results are accurate within the range of air temperature variability observed in different locations within the same urban area for all three tested cities. The performance of UWG is comparable to a more computationally expensive mesoscale atmospheric model and shows satisfactory performance for all weather conditions and for different reference sites.

UWG is robust and reliable software to capture urban heat island effect. The goal is to become the first urban design software to be used for policy making as well as in more accurate energy modeling with urban heat island effect as outlined in the following page.
